/**
 * Closed format-coverage registry
 *
 * One cell per (format, target). The Record over CanonicalFormat makes the
 * registry exhaustive at compile time: adding a value to photon-core's
 * OutputFormat without declaring how every target handles it fails tsc,
 * before any test runs. Removing a format from the type strands its entry
 * here and also fails tsc.
 *
 * Every cell is either a renderer (a real dispatch path in code) or an
 * explicit fallback (a documented downgrade) — there is no "absent" state,
 * which is what made silent drops possible. tests/contract/
 * format-coverage.test.ts cross-checks renderer cells against the actual
 * dispatch code so the registry cannot drift into fiction.
 *
 * Adding a new render target = adding it to RenderTarget, which forces a
 * decision for all 30 formats at once.
