Split the palette into two standalone stylesheets:
- colors.css — the 16 base16 slots (--base00..--base0F). This is the
entire theme swap contract; a generator (e.g. a stylix base16 scheme,
which is natively base00-base0F) replaces only this file.
- theme.css — the semantic layer (--bg, --purple, …) derived from the
base16 slots via var()/color-mix. Never changes on a swap.
Every page links colors.css then theme.css; theme.css does NOT @import
colors.css (that would re-bake the slots into it) — they're separate
dist outputs so a swap touches just colors.css. Pixel-identical refactor:
base16 defaults are Catppuccin Mocha and the three off-slot vars
(--crust, --muted, --subtext0) derive via color-mix reproducing their
exact prior hexes.
Wires colors.css through both build.mjs CSS entry lists, the
@hive/shared exports map, and all 7 page templates. css-vars.md + the
frontend.nix output-list comment updated.
