- Visible canvases (>=48px) are captured as PNG stills at capture time
(toDataURL, element-screenshot fallback for tainted/webgl) and emitted as
cid-carrying <img> elements filling the captured box, so canvas-driven
bands no longer render blank
- Source AND clone full-page screenshots now capture via CDP
Page.captureScreenshot with captureBeyondViewport: no scroll-stitching,
no scroll events, so scroll-linked animations can't smear mid-scrub
states into perceptual evidence (pixel-identical to the old path on
static pages; Playwright fallback retained)
- DittoLottie's runtime overlay stays position:absolute/inset:0 for its
whole life and the host carries data-ditto-lottie with a scoped
svg/canvas fit rule, so the runtime animation always fills the pinned
per-viewport box instead of escaping to aspect height
259 tests pass (12 new), typecheck clean.
