Keep shared offline defaults and download optional fonts into a validated cache with reliable export fallbacks. Prune stale Android DOM assets and refresh the smaller iOS editor bundles. Preserve lazy startup boundaries through direct shared exports and dependency-aware splitting. Add ESM graph and Chrome startup checks to prevent eager editor and font loading.
