Selected One Piece series now rank Double Packs (one-piece-tcg-db) directly after Boosters and before Decks. Existing Display, Case de Blisters and Blister priorities remain. Date and ID tie breaks and chronological browsing outside a selected series are unchanged. The server sorts before pagination; the app already displays that response order, so no mobile change is needed.

The API route regression failed before the fix and passes afterward. The actual priority SQL was executed in embedded PostgreSQL and returned the expected sequence. API build and full suite pass: 1647 passed, 19 skipped, zero failures.

PR prepared for staging, not merged or deployed. API deployment is required.
