Build four form primitives from Figma references with brand-aligned creative
decisions: restrained press states (scale-95 instead of highlight splashes),
clean iconless Switch, and consistent error states with inline warning icons.
Introduce form-control semantic tokens (--color-control-*) in tokens.css so
all form components share a single source for borders, checked states, focus
rings, labels, and errors. Retrofit Input to use these tokens instead of
direct palette references.
Update CLAUDE.md and ARCHITECTURE.md with token layer documentation, token
discipline rule (no palette references in components), and component tier
decision criteria.
