One tile under Settings → General → Storage: total local usage vs the browser's quota from navigator.storage.estimate(), the Chromium usageDetails breakdown when available (IndexedDB = sync cache + encryption keys + search index; Cache Storage = offline app files), and whether the browser granted persistent storage — green "Protected" or amber "May be evicted" with a "Keep my data" button that calls storage.persist(). That last bit is the useful diagnostic for the KE-1 storage-eviction cluster. No clear button: media lives in the browser's own HTTP cache (not in the estimate, and not clearable from a page), the crypto store must never be casually cleared, and the search-index clear already lives in Message Search. The About page's "Clear Cache & Reload" now says it deletes this device's encryption keys too. Hidden entirely when estimate() is missing.
