Production real-profile content is loaded via an explicit path, NOT the dev-only
OPENFUT_DEV_CONTENT_GAMES gate:
- Config.content_packs from env OPENFUT_CONTENT_PACKS (comma-sep file paths).
- CardDb::load_pack(path): merge an explicit CardDefinition[] production pack.
- app::build loads dev packs then production packs.
Preflight (app::build, always on): every owned_cards.card_id MUST resolve to a
loaded CardDefinition. A real profile with owned players but even ONE missing
definition fails LOUDLY instead of silently serving an empty /collection; an
empty owned_cards table (fresh DB / tests) passes.
2 preflight integration tests (missing def fails, loaded def passes). clippy
-D warnings clean; full suite 151 tests green.
