Brand-loop live test (SDS duplicate, plans/figma/brand-loop-test-plan.md)
proved the recolor chain end-to-end and surfaced three gaps:
- runtime now defines every declared composition variable as a CSS
custom property (document root at init + scoped sub-comp hosts in the
loader), so imported var(--slug, literal) fills resolve live — without
this the frozen literal always won and variable-driven rebranding
could not propagate. Slug kept byte-compatible with the figma
importer (parity test). render --variables overrides win.
- figma component --name: variant frames are often all named
'Platform=Desktop' and slug-collided across imports.
- imported fragments carry data-hf-snippet and the project linter skips
composition-root rules for them.
- /figma skill documents the field-tested non-Enterprise tokens path
(MCP get_variable_defs joined with REST boundVariables ids).
Shared-helper extractions (injectScopedStyles, flattenedRoot module,
parseHostVariableValues, rasterizeFallback, shapeCss) satisfy the
dedup/complexity audit the runtime changes tripped.
Validated live: brand-loop renders purple from the attribute alone (no
manual :root); 118 figma + 662 runtime/compiler + 331 lint tests green.
