Eidos Theming — Architecture Reference (moved)

The theming reference moved to the docs corpus (same §N numbering — every historical §N citation resolves there): docs/theming/reference.md

Section map:

§1 mental model · §1.bis theming lives in eidos, not morfo (the 2-of-3 derivation, the forbidden morfo-import, the canonical split)
§2 the CSS layers of the entrypoint · §3 the 7 token layers (scale → primitive → color → component → palette → variant → private)
§4 the 9 canonical color roles (mapping = THEME_BASE_COLOR_ROLES; convention ≠ authorship) · §5 the size canon (universal 1:1 size→font; label one step below; container cap at md; icon scale)
§6 naming conventions (the public-prefix table + the 7 strict rules)
§7 TSC → docs/canon/tsc.md · §8/§9 how-tos → docs/theming/guide.md
§10 runtime overrides + the builders (applyColorScheme, applyTypeScale) · §11 bundle strategy + eidos:purge · §12 validation tooling
§13 superseded (event:* scope) · §14 motion (the theming side: the --motion-scale-lift pickup) — the model lives in docs/theming/motion.md
§15/§17 comparison + FAQ → docs/theming/notes.md · §16 anti-patterns · §18 → TSC · §19 variants are eidos canon (EIDOS_VARIANTS)
§20–§38 standing-decision stubs; the chronicle is docs/theming/changelog.md (§23 scaling · §25 color model · §26 theme builder · §28 forced-colors · §29 depth · §30 shape · §31 structure · §32 focus ring · §35 scale canon · §36 floating gap · §37 touch-target · §38 state layer)
