Summary

  • improve Safari canvas and video snapshot performance by pre-resizing bitmap sources before createImageBitmap(...) on WebKit only
  • keep the native fast path unchanged for Chromium-based browsers
  • add a targeted rrweb test for the Safari fallback and regenerate the embedded rrweb bundle

Verification

  • re-checked the current PR surface and diff on 2026-03-30
  • this change is limited to the vendored rrweb subtree plus the generated bundle for the Safari snapshot fix

Release Notes

  • no changeset added intentionally: this PR updates vendored rrweb code and the generated bundle rather than introducing a separate package release from this branch

I re-checked the current PR surface. This change only updates the vendored rrweb subtree plus the generated bundle for the Safari snapshot fix; it is not intended to publish a separate package version from this PR, so I have intentionally not added a changeset. The remaining failing Vercel status is the external team-authorization gate rather than a code/test regression on this branch.
