Include the worked background-tint tier (borrow accent hue, fix L≈0.28 C≈0.045 → dim readable bg per hue) and the fg-vs-bg role split (bright accents for text, dim low-chroma tints for backgrounds). + +Two features it enables (both worth building): +1. Ramp generation (focus first): from a base color, generate its tonal ramp — base, +1/+2/+3 (lighter) and -1/-2/-3 (darker) — by stepping OKLCH lightness (and easing chroma) on a fixed hue. Term note: the whole family is a "ramp"/"tonal scale"; darker steps are "shades", lighter are "tints", gray-mixed are "tones" — so "ramp" or "scale" is the precise word, not "shades". +2. Harmonic fill: from a few chosen colors (e.g. slate blue + bg), generate a table of harmonic candidates (hue-angle schemes at matched L/C) to fill the missing palette slots. + +Open design problem to address in the explainer + the ramp feature: a background-over-text effect (highlight/region/isearch/hl-line) must stay readable for EVERY foreground that can appear on it — i.e. the worst-case (lowest) contrast across the whole set of element fg colors, not a single pair. The usable background lightness is therefore capped by the darkest/closest fg in that set. See the discussion for the proposed approach + UX (limiting-fg readout, live contrast floor, worst-case mask on the picker). + ** TODO [#C] Internet radio now-playing song :feature:music:emms: Show the currently-playing song while streaming an internet radio station. Lives in =modules/music-config.el= (EMMS + MPV backend, M3U radio stations). The track title comes from the stream's ICY metadata — EMMS exposes it via =emms-track-description= / =emms-playing-time= and updates it on the metadata-change hook; MPV reports the ICY title too. Add an option to show the song in the minibuffer (e.g. echo on track change, or an on-demand command). Consider also a mode-line indicator as a second surface. |
