#+TITLE: theme-studio — package faces (tier 3), starting with org-mode #+AUTHOR: Craig Jennings #+DATE: 2026-06-07 * Status Spec / Craig's first-round answers folded in (2026-06-07). Proposes a third tier for the theme-studio (scripts/theme-studio/) that lets a theme colorize package-specific faces, built one application at a time. v1 apps: org-mode (incl. org-agenda), magit, elfeed. Codex review incorporated (2026-06-07): added implementation phases, acceptance criteria, the package-face inventory source (hybrid, split), and state/export semantics. Rubric now =Ready=. All opens resolved (Craig, 2026-06-07/08): inheritance is modeled (show each face's resolved color in the table + preview, override what looks bad); inventory is hybrid-and-split (org/magit/elfeed bespoke first, generated all-package inventory as a later phase); the custom color picker is built after tier 3. Implementation tasks live in =todo.org=. * Background — the three tiers The theme-studio already models two tiers of faces: 1. *Syntax* — the font-lock / tree-sitter categories (keyword, string, type, comment, etc.), in the "code/color assignments" table. 2. *UI* — Emacs's built-in interface faces (cursor, region, mode-line, fringe, line numbers, isearch, and the rest), in the "ui faces" table with the live mock-frame preview. Tier 3 is *package faces*: faces a package declares with =defface= so a theme can color the package as it wishes. The running config has 1,146 such faces across 186 packages (magit 111, lsp-mode 97, telega 91, web-mode 82, org ~30 core, and a long tail). No theme colors all of them; quality themes hand-pick the packages the user actually lives in and theme those. This spec adds a tier-3 section to the tool, structured so applications are added one at a time. org-mode ships first. * Goal A new "package faces" section with: 1. An *application dropdown* — pick which package's faces to edit. v1 ships org-mode (including org-agenda), magit, and elfeed; the rest of Craig's packages (calibredb, ghostel, mu4e, IRC, org-drill, dirvish + dired, slack) follow one at a time. 2. A *face table* for the selected app — one row per face in the app's complete set, each with a foreground dropdown, a background dropdown, bold / italic toggles, an optional inherit, and a relative-height stepper, all drawing from the same palette as the other tables. Grouped, with a text filter for the large apps. 3. A *preview pane* for the selected app — a realistic mock of that package rendered with the live theme, the way the ui-faces mock-frame shows the UI faces in a buffer. org-mode gets a mock org document. The export (=theme.json=) gains a =packages= object so the build step can set these faces too. * UI placement A new top-level section under the ui-faces row: #+begin_example

package faces

[ application: (org-mode v) ]
left = the selected app's face table (fg / bg / B / I per face) right = the selected app's preview pane (e.g. the org document mock)
#+end_example Same two-column stretch layout as the ui-faces row, so the preview matches the table's height. * Data model A single data structure drives everything, keyed by application: #+begin_src js APPS = { "org-mode": { label: "org-mode", faces: [ // face, human label, default {fg, bg, bold, italic} ["org-document-title", "document title", {fg:"gold", bold:true}], ["org-level-1", "heading 1", {fg:"blue", bold:true}], ["org-level-2", "heading 2", {fg:"gold"}], ["org-level-3", "heading 3", {fg:"regal"}], ["org-todo", "TODO keyword", {fg:"terracotta", bold:true}], ["org-done", "DONE keyword", {fg:"sage", bold:true}], ["org-link", "link", {fg:"blue"}], // base `link` ["org-code", "inline code", {fg:"terracotta"}], ["org-verbatim", "verbatim", {fg:"steel"}], ["org-block", "src block body", {fg:"white", bg:"bg-dim"}], ["org-block-begin-line","block delim", {fg:"pewter", bg:"bg-dim"}], ["org-table", "table", {fg:"steel"}], ["org-date", "timestamp", {fg:"steel"}], ["org-tag", "tag", {fg:"tan"}], ["org-special-keyword","keyword/drawer", {fg:"pewter"}], ["org-meta-line", "#+meta line", {fg:"pewter"}], ["org-checkbox", "checkbox", {fg:"gold"}], ["org-headline-done", "done headline", {fg:"pewter"}], ], preview: "org" // names the preview renderer }, // magit, elfeed, ... added later with the same shape } #+end_src Defaults reference palette *names* (blue, gold, ...) resolved to hexes at load, so a curated app seeds sensibly from the current palette. The user reassigns any face from the palette dropdowns exactly like the other tables. State mirrors the other tiers: a =PKGMAP= of ={app: {face: {fg, bg, bold, italic, inherit, height, source}}}=, edited live, rendered into the table and the preview. The =APPS= block above shows ~18 org faces only as a shape illustration; the real org entry is the complete set below. ** Data model — org face set (complete) Per the completeness decision, org's table lists org's entire own =defface= set (org-faces.el + org-agenda.el), ~88 faces, grouped. Seed defaults for the prominent groups; the long tail seeds to fg or an =inherit= of its group base, which the user overrides. The groups (face names verbatim from the running Emacs): - *Document:* org-document-title, org-document-info, org-document-info-keyword - *Headings:* org-level-1 .. org-level-8, org-headline-todo, org-headline-done - *Status / keywords:* org-todo, org-done, org-priority, org-tag, org-tag-group, org-special-keyword, org-drawer, org-property-value, org-checkbox, org-checkbox-statistics-todo, org-checkbox-statistics-done, org-warning - *Links / dates / refs:* org-link, org-footnote, org-date, org-sexp-date, org-date-selected, org-target, org-macro, org-cite, org-cite-key - *Blocks / code / quote:* org-block, org-block-begin-line, org-block-end-line, org-code, org-verbatim, org-inline-src-block, org-quote, org-verse, org-latex-and-related - *Tables / columns:* org-table, org-table-header, org-table-row, org-formula, org-column, org-column-title - *Lists / meta / structure:* org-list-dt, org-meta-line, org-ellipsis, org-hide, org-indent, org-archived, org-default, org-dispatcher-highlight - *Agenda — structure & dates:* org-agenda-structure, org-agenda-structure-secondary, org-agenda-structure-filter, org-agenda-date, org-agenda-date-today, org-agenda-date-weekend, org-agenda-date-weekend-today, org-agenda-current-time, org-agenda-done, org-agenda-dimmed-todo-face - *Agenda — calendar & filters:* org-agenda-calendar-event, org-agenda-calendar-sexp, org-agenda-calendar-daterange, org-agenda-diary, org-agenda-clocking, org-agenda-column-dateline, org-agenda-restriction-lock, org-agenda-filter-category, org-agenda-filter-effort, org-agenda-filter-regexp, org-agenda-filter-tags - *Scheduling / deadlines / clock:* org-scheduled, org-scheduled-today, org-scheduled-previously, org-upcoming-deadline, org-upcoming-distant-deadline, org-imminent-deadline, org-time-grid, org-clock-overlay, org-mode-line-clock, org-mode-line-clock-overrun The org *preview* below stays a curated document exercising the prominent faces; the *table* carries the complete set so every face is assignable, even the ones the preview doesn't draw. magit and elfeed get the same treatment (complete own-defface set in the table, a bespoke preview for the common faces). * The org preview A mock org document painted from PKGMAP["org-mode"] plus the palette ground/fg. One bespoke renderer (=renderOrgPreview()=) drawing a representative document: #+begin_example #+TITLE: Project Notes <- org-document-title #+AUTHOR: ... <- org-meta-line / document-info * Inbox :work: <- org-level-1 + org-tag ** TODO Draft the spec <- org-level-2 + org-todo SCHEDULED: <2026-06-08 Sun> <- org-special-keyword + org-date ** DONE Ship the tool <- org-level-2 + org-done (headline-done) *** Heading three <- org-level-3 A line with =inline code=, <- org-code ~verbatim~, and a [[link]]. <- org-verbatim + org-link - [X] a checkbox item <- org-checkbox #+begin_src elisp <- org-block-begin-line (message "hi") <- org-block #+end_src <- org-block-end-line | name | hex | <- org-table (header row org-table-header) |------+---------| | blue | #67809c | #+end_example Each marked element is a span colored from the corresponding PKGMAP face. The preview rebuilds whenever a package face or the palette changes, same as the mock frame. org, magit, and elfeed get bespoke preview renderers (magit -> a status buffer mock, elfeed -> a search-list mock). Every *other* package is still fully themeable: its face *table* is always present and editable, only the rich *preview* is replaced by a generic fallback — each face's name rendered in its own colors on the ground. So a user can theme every package they have the moment its face list is added; the bespoke preview is a polish layer on top, not a gate. This is the v1 answer to "some will want to touch every package." * Export schema =theme.json= gains a =packages= key: #+begin_src json { "name": "dupre", "palette": [...], "assignments": {...}, "bold": [...], "italic": [...], "ui": {...}, "packages": { "org-mode": { "org-level-1": {"fg":"#67809c","bg":null,"bold":true,"italic":false,"inherit":null,"height":1.3}, "org-level-2": {"fg":"#e8bd30","bg":null,"bold":false,"italic":false,"inherit":"org-level-1","height":1.2}, "org-todo": {"fg":"#cb6b4d","bg":null,"bold":true,"italic":false,"inherit":null} } } } #+end_src =inherit= is optional and =null= when absent. When set, the converter writes =:inherit PARENT= plus only the overridden attributes. Only faces the user actually touched (or the curated defaults) are written. The build step's converter sets each as a normal face. Backward compatible: a file without =packages= loads fine. * Build-step consumption The eventual =theme.json= -> =dupre-*.el= converter already owns tiers 1 and 2. Tier 3 adds, per package face: #+begin_src elisp (org-level-1 ((t (:foreground "#67809c" :weight bold)))) (org-todo ((t (:foreground "#cb6b4d" :weight bold)))) #+end_src No new converter machinery — package faces are just more faces. This is the TDD-worthy part (JSON in, valid faces out), same as the rest of the converter. * Scope for v1 - Build the section, the app dropdown, and the face tables + previews for the three v1 apps: org-mode (incl. org-agenda), magit, elfeed. - org's table carries its complete own-defface set (~88 faces, grouped above), seeded with defaults; the org preview draws the prominent ones. - Every other installed package is reachable in the dropdown with an editable face table and the generic fallback preview, so any package can be themed. - Wire export/import of the =packages= key (with the optional =inherit= and =height= fields). - Leave the converter for the separate build-step task (Elisp, per Craig); the spec only needs the schema to be right. * Implementation phases Phased so each step ships without a broken intermediate, and the three bespoke apps don't wait on the all-package inventory. 1. *State + schema.* Add =PKGMAP= ({app:{face:{fg,bg,bold,italic,inherit,height,source}}}) and the =APPS= registry. Extend export/import with the =packages= key; old JSON (no =packages=) still imports cleanly. No UI yet. 2. *Curated app data.* Complete own-defface face lists + seeded defaults for org (incl. org-agenda), magit, elfeed, in =APPS= — including heading heights and the fixed-pitch inherits. Pure data. 3. *Package face table UI.* App selector; grouped rows; fg/bg dropdowns + bold / italic toggles + optional inherit + a relative-height stepper; per-face and per-app reset; a text filter (org/magit are large); a contrast readout per fg/bg. Built on a generalized face-control helper shared with the ui-faces table, not a fork of =uiSelect=. 4. *Org preview.* =renderOrgPreview()=, live, refreshing on palette/face change. 5. *Magit + elfeed previews.* Bespoke mocks (magit status buffer, elfeed search list). 6. *Generated all-package inventory* (the "theme every package" path). A build step queries Emacs for installed packages' faces grouped by package, writes a data file =generate.py= embeds; the dropdown then lists every package with an editable table + the generic fallback preview. Lands after phases 1-5 without blocking the three bespoke apps. 7. *Docs + validation.* README =packages= schema + inventory-refresh command; regenerate HTML; fixtures + manual checklist. Phases 1-5 deliver the three high-value apps fully; phase 6 opens the long tail; phase 7 documents. * Package face inventory source *Hybrid, split across phases.* Curated app metadata (org/magit/elfeed: complete face lists, seeded defaults, bespoke previews) is hand-maintained in =APPS= and ships in phases 2-5. A *generated* =PACKAGE_FACE_INVENTORY= — produced by a build step that asks the running Emacs for each installed package's faces grouped by package, written to a JSON/Python data file =generate.py= embeds — supplies the generic fallback packages and ships in phase 6. Why hybrid and split: the static generator can't discover packages at runtime in the browser, so "theme every package" needs a generated inventory; but making the full inventory a prerequisite for the three bespoke apps invites the scope explosion the review flagged. Splitting it lets v1's core ship first; the inventory is additive. The generated inventory is an *input artifact* to =generate.py= (a committed data file refreshed by an explicit command), never browser-side discovery. The refresh command's dependency on a loaded Emacs config is documented. Decided (Craig, 2026-06-08): hybrid-and-split, as above. * State and export policy Each package face object carries a =source= marker so export can tell a seeded default from a user edit from a deliberate clear: #+begin_src js { fg:"#67809c", bg:null, bold:true, italic:false, underline:false, strike:false, inherit:null, height:1.0, source:"default" } // underline / strike: booleans -> the converter writes :underline t / :strike-through t // height: float multiplier off the base font (1.0 = unchanged); see Relative height // source: "default" (seeded) | "user" (edited) | "cleared" (user removed a default) #+end_src Export policy: - Write =default= and =user= entries. - Write =cleared= entries — they must suppress a curated default on reload. - Omit untouched faces that have no default. - When =inherit= is set, write =inherit= plus only the explicit overrides. - Write =height= only when it differs from 1.0. - Preserve package faces present in an imported file but absent from the current inventory (or warn) — don't silently drop them. Import tolerates a missing =packages= key, unknown app keys, unknown face keys, a missing =inherit=, and a missing =height= (defaults 1.0). A deleted palette color leaves package face references in the same "(gone)" recoverable state syntax colors use. Inheritance cycles are rejected (treated as no inheritance) during preview resolution. * Relative height Some faces want to be bigger than body text — org headings above all, also =org-document-title=. A face's =height= field is a *float multiplier* off the base font (=1.3= = 1.3× the running font, whatever it is), never an absolute point size, so it stays portable across fonts and machines. =1.0= means unchanged. The base monospace family is *not* a theme/tool concern — it lives in =modules/font-config.el=; the tool owns only relative size. *Height does not cascade through =inherit=.* This is the one attribute resolved directly off the face, not through its inherit chain. Emacs multiplies float heights along an inherit chain, so a level-2 that inherits level-1 (1.3) and also sets 1.1 would render at 1.43 — almost never what's wanted. Headings should each size off the *body*, so the seeded defaults set =org-level-1= 1.3, =org-level-2= 1.2, =org-level-3= 1.15, etc., each independent, and the tool reads =height= from the face while still resolving *color* through inherit. - *Schema:* the =height= float on the face object (above), default 1.0, omitted from export when 1.0. - *UI:* a small numeric stepper in the face row (range ~0.8–2.0, step 0.05); meaningful only for the size-bearing faces but shown on every row at 1.0. - *Preview:* the row renders at the scaled =font-size= so a heading visibly grows in the mock. - *Converter:* writes =:height 1.3= into the face spec when ≠ 1.0. Related, same mechanism: org's mixed-pitch faces (=org-block=, =org-code=, =org-verbatim=, =org-table=, =org-meta-line=, =org-date=) seed =inherit: "fixed-pitch"= so they stay monospace when a buffer switches to a proportional font via =variable-pitch-mode= / =mixed-pitch=. The proportional family itself stays in =font-config.el= (the presets already carry =:variable-pitch-family=); the tool only carries the fixed-pitch inherit relationship, shown like any other inherited value. * Acceptance criteria - Existing =dupre.json= (no =packages= key) imports cleanly. - Export includes =packages= once defaults or edits exist; =fg/bg/bold/italic/inherit/height/source= round-trip through import/export. - A face =height= renders as a scaled font-size in the preview (heading visibly grows) and is read off the face, not cascaded through =inherit=. - org, magit, elfeed appear in the app selector with complete grouped face tables. - (phase 6) generic inventory packages appear with editable tables + fallback previews, the fallback visibly labeled as generic. - A palette color update propagates to package faces the same way it does to syntax / ui faces. - =python3 scripts/theme-studio/generate.py= rebuilds =theme-studio.html=. - README documents the =packages= schema, inheritance, and the inventory source. * Extensibility (adding the next app) 1. Add an entry to =APPS= (label, curated face list with palette-name defaults, preview key). 2. Optionally write a bespoke preview renderer; until then the generic fallback renders. 3. Nothing else changes — the dropdown, table, export, and import are all data-driven off =APPS= / =PKGMAP=. * Agreed decisions Craig's answers to the first review round, baked in (the body sections above reflect these; this records the decisions): 1. *Curated set is complete, not iterative.* For org, list its *entire* own defface set (org-faces.el + org-agenda.el), ~88 faces, not a hand-picked ~18. The user wants every choice present, not a set that grows on demand. See "Data model — org face set" for the full grouped list. 2. *Seed curated defaults.* Seed sensible fg/bg and weight per face (headings, title, TODO/DONE bold; agenda dates and deadlines colored by role). The user reassigns from there. 3. *App order: org, magit, elfeed for v1.* Then the rest one at a time, drawn from the packages Craig actually runs: calibredb, ghostel, mu4e, the IRC client, org-drill, dirvish + dired, slack. A finite "most-used" list gets picked later; we do not try to do everything at once. 4. *Generic fallback is real, not display-only.* Any package not given a bespoke preview still gets a fully editable face table (so a user can theme *every* package they have); only the rich preview is missing, replaced by a swatch-in-context fallback. Bespoke previews ship for org, magit, elfeed. * Inheritance representation (decided) Each face carries an optional =inherit= field naming another face (or =null=). The face's own =fg/bg/bold/italic= are *overrides* layered on top of what it inherits. #+begin_src js ["org-level-2", "heading 2", {inherit:"org-level-1", fg:"gold"}] // exports as: (org-level-2 ((t (:inherit org-level-1 :foreground "#e8bd30")))) ["org-agenda-date-today", "agenda today", {inherit:"org-agenda-date", bold:true}] // exports as: (org-agenda-date-today ((t (:inherit org-agenda-date :weight bold)))) #+end_src *Decision (Craig, 2026-06-07): model inheritance, show the resolved result, override what looks bad.* The point is to see what a face ends up looking like when it inherits, judge it in the preview, and fix only the ones that look wrong: - Each face's *effective* color is resolved through its inherit chain and shown in its table row, visibly marked "inherited from " so it reads as not-explicitly-set. The face's own =fg/bg/bold/italic= are overrides layered on top. - The mock preview on the right renders every face with its effective color, so inherited faces are judged in context, not in the abstract. - Overriding is one action: assign a color (or toggle weight) and the row flips from inherited to explicit (=source: "user"=), shown at once in the table and preview. - Export writes =:inherit PARENT= for faces left inherited (carrying the relationship, so they follow the parent the theme also sets) and explicit attributes for the ones overridden — never a frozen copy of an inherited color. Seeded defaults express the inherit relationships org itself uses out of the box (heading levels off a base, =org-agenda-date= variants off =org-agenda-date=, =org-code= / =org-verbatim= off =fixed-pitch=), so the table opens showing org's real cascade, which the user then tunes. Inheritance cycles resolve to no inheritance. * Custom color picker (proposal) Craig wants a custom in-page color picker to replace the native browser swatch. The native == opens the OS color chooser, which the page cannot size or restyle; a custom picker is the only way to get a larger, on-theme picker and to show the palette/contrast in the picker itself. Proposed widget — a popup anchored to the swatch, drawn in-page: - A *saturation/value square* (click or drag to set S and V) plus a *hue slider* down the side. Standard HSV picker geometry. - A *hex field* synced both ways with the square/slider (already exists in the add-color row; the picker writes to it). - The current *palette* shown as clickable chips along the bottom, so picking an existing color is one click and the overlap problem (many roles, one color) is visible while choosing. - A live *contrast readout* against the current background (ratio + AAA / AA / FAIL) updating as the color moves, so a color is judged for legibility at pick time, not after assignment. - Sized generously (the native popup's size was the original complaint); opens on click of the swatch, closes on pick or click-away. Implementation: ~120 lines of vanilla JS/canvas (or CSS gradients) for the square + slider, reusing the existing =rl()= / =contrast()= / =rating()= helpers for the readout and =normHex()= for the field sync. No dependency. It replaces the == in the add-color row and, later, becomes the picker the package-face dropdowns can also invoke. It stays *off* the tier-3 critical path: a separate task before or after the package-face build, not folded into it, since folding it in widens the blast radius for no dependency benefit. Build it only sooner if package-face editing proves painful with the native swatch. Decided (Craig, 2026-06-08): after tier 3, as its own task. * Files touched - =scripts/theme-studio/generate.py= — the section, =APPS= data, the package face table, =renderOrgPreview()=, export/import of =packages=. - =scripts/theme-studio/theme-studio.html= — regenerated. - (later) the =theme.json= -> =dupre-*.el= converter (Elisp) — consumes =packages=. * Review dispositions Codex review (2026-06-07), =Not ready=. Findings processed: - *Modified — generated inventory (high, blocking).* Codex recommended a hybrid inventory so every installed package is reachable. Accepted the hybrid, but *split* it: the generated all-package inventory is its own phase (6), after the three bespoke apps (phases 1-5), rather than a v1 prerequisite. Reason: Codex named scope explosion as the main risk, and gating org/magit/elfeed on a full-inventory mechanism is exactly that. The split keeps v1's core shippable and makes "theme every package" additive. Confirm-with-Craig flagged as an open. - *Modified — preview depth (UX obs).* Codex suggested level 4-8 examples in the org preview. The preview stays a curated document drawing the prominent faces (incl. a couple of deeper levels as representative); the complete level set lives in the *table*, which is where every face is assignable. A full 8-level preview block would bloat the mock without adding assignability. Everything else in the review accepted as written: implementation phases, acceptance criteria, the =source= state field + export policy, curated-vs-complete wording, keeping the custom picker off the critical path, unknown-import preservation, the test-strategy fixtures, and the UX/architecture/robustness observations (grouping + filter, reset controls, package-fg/bg contrast readout, generalized face-control helper, package style kept inside the package object, "(gone)" recoverable state, inheritance-cycle rejection). * Review and iteration history ** 2026-06-07 Sun @ 18:17:14 -0500 — Claude Code (emacs-d) — author + responder - *What:* Folded Craig's first-round cj-comment answers into the body. Curated org set changed from ~18 to org's complete own-defface set (~88, grouped, incl. org-agenda). v1 apps fixed to org/magit/elfeed with the rest deferred to a one-at-a-time list. Generic fallback clarified as a fully editable table for every package (only the rich preview is bespoke). Answered the inheritance question with an optional =inherit= field (absolute-default, opt-in cascade) and added it to the schema. Added a custom-color-picker proposal at Craig's request. Converted Open questions to Agreed decisions; two genuine opens remain (inheritance confirm, picker timing). - *Why:* Craig answered the five open questions inline and asked for the spec-response fold plus a custom-picker proposal. Completeness over iterative growth was his explicit call on the curated set. - *Artifacts:* This spec. The converter language (Elisp) confirmed by Craig. Note: Craig referenced a Codex spec review, but no =theme-studio-package-faces-review.org= (or any =*-review.org=) exists in the repo — the review file could not be found, so only the author-side cj-comment fold was done; the Codex review remains to be processed when its file is located. ** 2026-06-07 Sun @ 18:20:16 -0500 — Codex — reviewer - *What changed or was recommended:* Created the missing formal review and marked the spec =Not ready=. The review recommends adding implementation phases, acceptance criteria, an explicit package-face inventory source, and default/user/cleared/inherited export semantics. - *Why:* The direction is coherent and the first-round decisions are folded in, but v1 now depends on behavior that is not yet implementable from the current static generator without a defined inventory and state/export contract. - *Artifacts:* [[file:theme-studio-package-faces-spec-review.org][theme-studio-package-faces-spec-review.org]] ** 2026-06-07 Sun @ 18:28:02 -0500 — Claude Code (emacs-d) — responder - *What:* Ran spec-response against the Codex review. Added Implementation phases (7), Package face inventory source (hybrid, split), State and export policy (=source= field + export rules), and Acceptance criteria. Wove in the UX/architecture/robustness observations. Two reasoned modifies (generated inventory split into its own phase; org preview stays curated rather than all-8-levels), everything else accepted — see Review dispositions. Status moved to =Ready with caveats=. Deleted the review file. - *Why:* The four blocking findings were real implementation-contract gaps; the inventory split answers Codex's own scope-explosion warning while still reaching "theme every package." - *Artifacts:* This spec (Review dispositions section); review file deleted per the spec-response close-out. Three opens remain for Craig (inheritance confirm, hybrid-inventory confirm, picker timing). ** 2026-06-08 Mon @ 00:12:38 -0500 — Codex — reviewer - *What changed or was recommended:* Reran spec-review after the response pass. Assigned rubric =Ready= and did not create a new review file. The previous blockers are now addressed: implementation phases, acceptance criteria, hybrid/split inventory source, package-face state/export semantics, task tracking, and the open inheritance/inventory/picker decisions are resolved. - *Why:* The spec now gives an implementer concrete behavior, phase boundaries, validation criteria, and deferred-work handling without forcing product decisions during implementation. - *Artifacts:* This spec; implementation tasks in [[file:../../todo.org][todo.org]]. ** 2026-06-08 Mon @ 00:38:23 -0500 — Claude Code (emacs-d) — author - *What:* Added a relative =height= field to the face schema (float multiplier off the base font, default 1.0, omitted at 1.0), a new "Relative height" section, a per-face stepper in the table, preview scaling, and converter output. Established the rule that =height= is read off the face and does *not* cascade through =inherit= (Emacs multiplies float heights along the chain). Noted the mixed-pitch =fixed-pitch= inherits as the same-mechanism companion. Brought Phase 1's shipped schema plumbing in line with the new field. - *Why:* Craig asked to fold height in — it matters for org headings above all. Font *family* stays in =modules/font-config.el=; the theme owns relative size and the fixed-pitch inherit relationships only. - *Artifacts:* This spec; =scripts/theme-studio/generate.py= phase-1 plumbing.
