The previous design kept a single global Map<cacheKey, objectURL> with an LRU cap of 150 and aggressively revoked the oldest URL on overflow. On libraries with more than 150 cached covers (artist + album grids quickly exceed that), an in-use URL would get revoked because a different consumer pushed it out of the cache, producing the "Failed to load resource: blob:..." flood that several users have reported. Refactor the cache to be blob-centric: - Public API is now getCachedBlob() returning the Blob itself. - In-memory LRU now holds Blobs (cap 200), not URLs. Map-entry eviction drops the strong reference and lets the GC free the Blob once no consumer (object URL, <img>, <canvas>) still holds it. No revoke choreography needed. - useCachedUrl creates its own URL.createObjectURL on blob arrival and revokes it on cleanup with a 500 ms grace delay so the DOM <img> has time to finish decoding the URL we just took away. - All existing callers keep their string-returning API; no call-site changes outside the hook itself.
