base.css shipped all 31 Radix donor scales, but the theme's roles only
reference 9 (gray green indigo orange plum purple red slate teal). The
other 22 were dead weight on every page: no component references raw
--scale-* (they use --color-{role}-*), and runtime theming builds from JS
scale data and writes RESOLVED values (build-scheme: variables[k]=hex),
so it never reads the CSS scale tokens.
renderThemeCss now emits only role-referenced scales by default; the full
31-scale donor palette ships opt-in in generated/palette.css (new
renderColorPaletteCss). The CSS contract stays the full vocabulary
(apps can still override any scale; load palette.css to use the extra 22).
base.css 53.7→35.4 KB gz. Monolith (every page) 54.4→36.2 KB gz —
combined with Phase 3, 113.5→36.2 KB gz total (−68%). Verified: roles
resolve (primary=purple, button bg correct), pruned scales empty on
regular pages, restored on /temas/color via palette.css. Updated the
contract test to verify coverage against the full palette. check clean
(13 errors are untracked heroscrolling demo + gitignored tmp/lexical);
eidos suite at baseline (192/195, 3 pre-existing words failures).
