🔮 Speak the incantation — any binder, any card

Every card in the universe has one 7-word name. Speak it here. If we know the seed, the card opens instantly. If we don't, we walk the federation (RAR, RAPPcards, Red Binder, plus anyone who publishes a seed-index.json) and pull the card directly from raw.githubusercontent.com. Zero coordination required.

Federation walk order: local → RAR → RAPPcards → other peers. The first binder that owns the seed wins. See SPEC.md §5.4.

🔗 Cross-binder handoff

Share any card with any binder — they all speak the same incantation language.

Local-first. Your binder lives in IndexedDB on this device. Export is SPEC-compatible — you can import the same file into RAPPcards or RAR. The schema is rappcards-binder/1.0. Foreign cards (from any binder) are stored with their full card data so they work offline.
