Live quota (StorageManager API)

Measuring…

IndexedDB API — practical limits

No fixed size in the spec — quota is per origin and depends on disk and browser.
Chrome / Edge: often up to ~60% of disk for an origin (shared pool; lower in Incognito).
Firefox: share of free disk; related hosts (eTLD+1) often capped around ~2 GB as a group.
Safari: often ~1 GB class limits; iOS may clear data after inactivity; private mode is very limited.
Eviction: under pressure, browsers may delete least-recently-used site data unless navigator.storage.persist() was granted.
Kawoko: image bytes go to IndexedDB; small metadata stays in localStorage (~5–10 MB typical hard limit).

Web Storage Quota API

navigator.storage.estimate() → usage (bytes used) and quota (approx max).
navigator.storage.persist() → ask browser not to auto-evict.
navigator.storage.persisted() → whether persist is already granted.
Best on HTTPS (e.g. kawokowebz.rsu1.uk) or localhost. Not a substitute for catching QuotaExceededError on write.
