Integration only — DO NOT MERGE. The owning PRs remain the merge/release units. This PR remains a draft.

Refreshes the follow-up integration snapshot onto main ca9331be after squash-merge #321. Its two old commits are absent from the rebuilt history. The rebuild uses one linear integration commit; it creates no Git merge commits.

Includes current runtime/registry owning changes from #317, #318, #319, #320, #322, #323, #324, #325, #326, #327, #328, #329, #330, #331, #332, #333, #334, #335, #337, #338, #340, #341, #344, #345, #347, #348, #349, #350, and the split Remix slider draft #352. The new #334 and #352 slider source/test blobs match their owner heads exactly.

Stacks preserved: #320 → #328; #335 → #337; #347 → #341 → #345 → #348. #348 inherits #347's API without duplicate Naked UI commits. #342/#343/#346 are adoption drafts above this hub, blocked on published naked_ui 1.3.0 and Remix 1.0.0-beta.14 and approved floor updates. No release or registry-floor change is part of this refresh.

The runtime tree preserves Hero's prior conflict resolutions, including the accordion reduced-motion regression, the select arrow counts (8→7, 20→19, 11→12), combined effect/state scopes, all CHANGELOG entries, and generated HeroUI radio/switch adapters. The refresh only formats the combined consumer checker; it does not invent new regression fixes. Deferred ADR/AGENTS consolidation and the held HeroUI ADR rewrite are not applied.

Validated with pinned Flutter 3.44.0:

• Owning slider probes: 31 Naked UI geometry/lifecycle tests and 15 Remix geometry tests pass.
• Full Naked UI suite: 1,157 pass, 3 skips.
• Full Remix suite: 3,162 pass.
• HeroUI installed-gallery wiring: both new tests pass after CLI installation; replacing only the gallery entry point with its pre-adoption version makes both fail at runtime (no compile failure).
• melos run ci:checks: passes, including docs and registry derivation checks.
• fix(remix_cli): enforce registry ownership across installs #333 merges cleanly with new main under git merge-tree; its ownership preflight and test(registry): amortize checkout CLI startup #351 compiled-consumer path are both retained.
• Mutation proofs after restacking: reverting the Remix slider implementation fails 14/15 geometry cases at runtime; reverting toast intrinsic layout fails its runtime tests; restoring the avatar radius bug fails the custom-token assertion; serializing production dispatch fails the overlap assertion.

GitHub Checks validate this refreshed integration head separately. This PR remains DO NOT MERGE regardless of its check state.
