Projeção de tokens de design

Design-token projection is the subset-value invariant a consuming leaf must satisfy against the canonical token source: it may ADD its own page-only tokens but may NOT redefine a canonical token to a different value (a divergence is reported as design-token projection drift), paired with a reverse-flow tripwire that also flags superseded brand-color literals reappearing as hardcoded values, keeping any downstream generative tool off the design truth path.
