Panel chrome, filetype colours and the full 725-entry icon table. The icon table is Yazi's preset with every glyph colour remapped onto the Gruvbox palette: nearest neighbour in Oklab with lightness weighted down so hue drives the match, chromatic and greyish sources matched from separate pools, and target tones below 3:1 contrast on #282828 excluded. 221 upstream colours collapse onto 19 Gruvbox tones, dimmest icon at 3.48:1. regen-icons.py reproduces the mapping against a newer Yazi preset. Uses the current schema ([mgr]/[tabs]/[pick]/[cmp]), not the pre-25.x one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
