refactor(css): migrate all hardcoded colours to primitives (CSS → zero literals)
Move every non-structural colour literal in source CSS into the primitive
palette and reference via var(--p-*):
- 194 hex + 139 rgba() across 38 files replaced
- 90 new primitives added (brand azure/red, violet/indigo, cyan, pink,
emerald, slate, navy, Notion paper, illustration art, vendor/OS-media)
- near-duplicate neutrals snapped to existing ramp values
- coloured rgba() alpha tints -> color-mix(in srgb, var(--p-*) N%, transparent)
- structural rgba(0,0,0/255,255,255) and comment breadcrumbs left intact
Source CSS now contains zero hardcoded colour outside primitives.css.
Build + theme-lint pass; every var(--p-*) reference resolves.
