- Add ResizeObserver (JS observeResize/unobserveResize + C# OnWidthChanged)
so _elementWidth stays current after window resize, fixing hover indicator drift
- Move _isSeeking = true before capturePointer await so a fast mobile tap
that fires pointerup mid-await still commits the seek
- Replace all Duration!.Value null-forgiving dereferences with explicit
Duration is > 0 guards in all four pointer event handlers
- Silence post-dispose resize callback rejections with .catch(() => {})
DOM bar chart with clip-overlay progress split; pointer-capture drag;
WaveformProfile fetched on load (fire-and-forget, cancellable); flat
fallback when no profile; small lazily-loaded waveformSeeker.js for
getBoundingClientRect and setPointerCapture.
