* feat(career): practice invitations — closest stamps + bring-these-up
Career v3, WS1. The passport now points at the practice that pays:
- Stubs carry next_star_at (the same primitive _stars() uses) and each
passport exposes `nearest`: the top 3 non-qualifying songs by distance
to their next star, in the worklist order.
- "Closest stamps" strip above the shelf: the in-progress graded
passports nearest to minting, each row naming the ask — N more songs
(with the nearest title + best %) or the blocking Virtuoso drill.
Rows open the passport.
- "Bring these up" list on the stubs page of in-progress passports;
earned pages stay memorabilia (no homework on a won badge).
- Invitation-voiced throughout: no meters, no completion pressure.
