 /**
  * One cached FX quote: `1 baseCurrency = rate × currency`.
  *
  * A row per quote rather than one JSON blob per base — the table is written whole and read whole,
  * but rows let SQLite do the "newest fetch for this base" bookkeeping without decoding a blob, and
  * keep the schema inspectable. No foreign key: currencies here are provider codes, not workspace
  * rows, and the cache must survive a workspace wipe.
