Second step of the visual-redesign (tokens -> primitives -> surfaces):
a small set of shared, token-driven primitives in @trails-cool/ui so
both apps compose from one styled vocabulary instead of hand-rolling
bg-white/text-gray-* per screen.
- @trails-cool/ui now ships React components (Button variants+sizes,
Badge tones, Card raised/subtle, Input) plus a tiny cn() helper.
React is a peer dep; package builds with no bundling step.
- Co-located jsdom unit tests (@testing-library/react) assert roles,
token classes, variant switching, and behavior — run in the existing
Unit Tests gate, cross-platform, no snapshot baseline needed.
- Tailwind @source directive in both apps' styles.css so the package's
token utility classes get generated.
- Dev-only /dev/ui gallery route in the planner renders every primitive
in all states — a zero-dependency stand-in for Storybook. Excluded
from production builds (NODE_ENV guard in routes.ts).
No app surfaces are refactored yet; adopting the primitives in the
topbar/sidebar/etc. is the surface task groups.
