Documentation and repository tooling only — no runtime changes.
Link a live CodeSandbox from the top of the README, from the quick start, and from the virtualizer guide, so every example can be tried without cloning anything.
Finish the virtualizer guide. It now shows the exported useMergedRef solving the one-node-two-owners problem, and points at example/demos/Virtualized.tsx, which pages 5000 rows while keeping about fifteen of them in the DOM.
Document the release process end to end — changeset, version bump, tag, GitHub release — including the two things that are easiest to get wrong: NPM_TOKEN needs write access to the whole @vmariev scope rather than to a list of packages, and a published version can never be replaced.
Remove the unused release script. It published outside the workflow, which skipped the provenance attestation and made a duplicate publish of the same version possible.
