iris 09787dd1c3 refactor(frontend): base16 theme contract in a swappable colors.css
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.

/* Semantic theme layer — derived from the base16 contract in
`colors.css`. This is what the app references (`--bg`, `--fg`,
`--purple`, …); page CSS must use these names, never literal colours
and never the raw `--baseNN` slots.
Standalone stylesheet, linked by every page right AFTER `colors.css`
(which defines the `--baseNN` slots these rules resolve against). Kept
separate from the page bundles — esbuild would otherwise inline an
`@import` and bake the palette into every CSS bundle.
A theme swap touches only `colors.css` (the 16 base16 slots); this
derivation layer never changes. See docs/web-ui/css-vars.md. */
