Three small tranches out of playerStore.ts:
- src/utils/waveformParse.ts — waveformBlobLenOk + coerceWaveformBins (the
parser that handles number[] / Uint8Array / ArrayLike payloads Rust
serializes as).
- src/utils/normalizationCompare.ts — normalizationAlmostEqual (tolerant
null-aware dB comparison).
- src/utils/seekErrors.ts — isRecoverableSeekError (retry classifier for
the Rust seek pipeline).
Each gets focused unit tests. All four were file-private, no external
callers — pure code move. playerStore 3556 → 3516 LOC.
