OnboardingTour.tsx — minimal Driver.js-style spotlight + tip
without an external dep (driver.js is 18KB; this is ~3KB and matches
the blueprint design language). Fires once per browser (localStorage
flag fm.canvas.tour.seen). Five steps:
1. Mission Control — start every morning here
2. Approvals — anything waiting on you
3. Process Studio — describe → publish in five phases
4. Team Chat — replaces the 'quick Teams ping'
5. Command Assistant — plain-language actions
Keyboard nav: Enter / → next, ← back, Esc skip. Click backdrop also
skips. Only mounts when authed and not on login/sso-callback. Dark
theme colours included.
31/31 vitest pass.
