+The Dupre theme ships in the dotfiles repo and is applied with the `set-theme` script (installed via the `hyprland` dotfiles). Its files live under `~/.dotfiles/hyprland/.config/themes/dupre/` and cover foot, fuzzel, waybar, dunst, hyprlock, and Xresources.

 * Weighting criteria (compare on these)
 - Daily-use win: does it remove a real friction, or is it novelty? "Answers in one command what took a pipeline" (dust) beats "same answer, prettier" (gping).
 - Workflow fit: Emacs (dired, vterm, magit) and tmux already own many niches. A candidate duplicating them adds maintenance surface without adding capability (see: terminal tabs/splits, broot vs dired+zoxide).
-- Theme-system fit: can set-theme drive it (INI/TOML include, runtime color escape, reload signal)? Tools that can't follow dupre/hudson stay second-class.
+- Theme-system fit: can the Dupre apply path drive it (INI/TOML include, runtime color escape, reload signal)? Tools that cannot follow the desktop palette stay second-class.
 - Packaging: official repo > AUR > git build. Every step down adds update fragility to fresh installs.
 - Migration cost: config translation, muscle-memory retraining, installer changes. Cost scales with how load-bearing the incumbent is.

 ** Phase 11b — Prototype fidelity pass (added 2026-07-08)
 Added mid-build from Craig's live-board review: phases 7-10 delivered E5's structure and behavior but rendered subpanel metrics as one-line list rows (the sibling panels' idiom) instead of the prototype's instrument-card grid; the per-phase screenshot checks verified structure, not presentation. Scope: card-grid subpanels (4-up metric cards — big-number value, caption line, progress bars, radial gauges for scrub cadence and NVMe wear, status chips, corner lever key), two-row selector tiles with compact count chips, subpanel attention/ok/fixable/watch header line, evidence digests as full-width rosters under the grid. Engine and viewmodel contracts unchanged; =gui.py= layout + =panel.css=. Sequenced before Phase 12 so the AT-SPI smoke targets the final layout. Verification is a pixel-level comparison against the settled E5 render (headless Chrome), not structural spot checks.
