P0: Next.js shell — tokens, motion, SlidePanel, LeftRail, auth plumbing

- Tailwind v4 @theme block encoding all spec §2 tokens; full §3 keyframe
  inventory with prefers-reduced-motion handling; Geist vendored (air-gap)
- SlidePanel width-animation primitive (component-tested: exit-transition
  unmount, fixed-width inner content, a11y region semantics)
- session-key.ts mirroring the Rust codec + URL-param encoding; nuqs
  panel-params with spec ?sessions=1 flag shape and routines->scheduled alias
- Zod-typed API client; httpOnly cookie session bridge (/auth/session);
  login page; (workspace) layout with LeftRail roster/nav/user; Team and
  Credits pages on real endpoints (+ GET /api/team/members in tc-api)
- Vitest + Testing Library harness (26 tests); ESLint max-lines 1250 +
  no-warning-comments mirroring the CI gates
