Across-the-board sluggishness was every cold-cache tap doing one network round trip while the user waits. SWR helps on re-visits but the first time you tap a tile from home you eat the latency. MetadataPrefetcher listens to homeProvider. When /api/home returns, it fires fire-and-forget reads on albumProvider + artistProvider for the top-N items in each home section (recently added, rediscover, most played, last played). Each provider read triggers the existing cold-cache path, which writes to drift. By the time the user actually taps a tile, it's already a drift hit and the detail screen renders instantly. Cap N=8 per section (covers what's visible on a typical phone without scrolling). Set spans dedupe across sections so popular artists don't get fetched five times. Errors are swallowed — a failed prefetch is silent and the tile falls back to its on-tap fetch behavior. Wired alongside the existing audio prefetcher in app.dart's postFrameCallback.
