- loadManifest() goes through DataCache.fetchWithFallback: the file list is
written to IDB and survives SW-cache eviction; a run with the reduced
fallback set is flagged and shown as degraded (new i18n en/ru/cu).
- 404 answers are counted as 'missing' (deployment drift) with a
preload-missing diag entry, instead of silently reporting Done.
- preload() is re-entrancy safe: concurrent calls join the in-flight run.
- versions.json is loaded once per session (was fetched per translation).
- Write-through failures in fetchWithFallback()/fetch() log idb-write-fail.
- preload-manifest.json SW route is NetworkFirst (fresh coverage online).
- Manifest now also covers the shared/lives + shared/commands fallbacks.
