/**
 * Leaf module holding the default embedding model + dimensions.
 *
 * Extracted so schema helpers (pglite-schema.ts, postgres-engine.ts) +
 * registry helpers (search/embedding-column.ts) can import the constants
 * without pulling the full AI gateway (which loads every provider SDK).
 *
 * gateway.ts re-exports these so existing import sites keep working.
 *
 * Single source of truth for "what does a fresh brain look like when the
 * user passes zero flags?" Touching these defaults touches every fresh
 * install AND every doctor consistency check.

// LEGACY CONFIGLESS RUNTIME FALLBACK — not the new-install default anymore.
