## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Inspect the latest CodeRabbit review on PR #31, evaluate each actionable comment against the current branch, implement valid fixes, verify the changes, and prepare PR thread updates.
<!-- SECTION:DESCRIPTION:END -->

## Implementation Plan

<!-- SECTION:PLAN:BEGIN -->
1. Inspect latest CodeRabbit review on PR #31 and separate valid action items from non-blocking suggestions.
2. Add regression coverage for any real bugs before changing production code.
3. Implement the minimal fixes for confirmed issues in runtime, renderer modal flow, and test fixtures.
4. Run targeted tests plus repo-native verification lanes.
5. Update PR threads with fix status and rationale for any comments not actioned yet.

## Implementation Notes

<!-- SECTION:NOTES:BEGIN -->
Implemented and pushed commit 207151db to PR #31.

Replied in-thread to the CodeRabbit comments for YouTube host matching, duplicate picker submissions, and missing MediaDetailView test fixture videoId fields.

Follow-up scope added: update release-facing docs/changelog for the YouTube subtitle picker work and run a release-readiness gate before handoff.

Added release-facing docs/changelog updates in commit b7e0026d and pushed them to PR #31.

Ran the release-readiness gate: changelog:lint, changelog:pr-check, verify:config-example, typecheck, test:fast, test:env, build, test:smoke:dist, docs:test, docs:build.

## Final Summary

<!-- SECTION:FINAL_SUMMARY:BEGIN -->
Assessed the latest CodeRabbit review on PR #31 and applied the confirmed fixes. Tightened `isYoutubeMediaPath()` to match only exact YouTube hosts or subdomains with a regression test for `notyoutube.com`, added an in-flight guard plus temporary control disabling to the YouTube track picker with a duplicate-submit regression test, replaced the picker empty-state `innerHTML` fallback with explicit DOM construction, and added the missing `videoId` fields to the `MediaDetailView` test fixtures. Verified with targeted Bun tests and the `runtime-compat` verification lane (`build`, `test:runtime:compat`, `test:smoke:dist`).

Updated `README.md`, `docs-site/usage.md`, and `changes/2026-03-23-immersion-youtube.md` so the PR is release-facing and user-visible surfaces describe the YouTube subtitle picker flow plus its latest hardening.

Release-readiness checks passed locally: `bun run changelog:lint`, `bun run changelog:pr-check`, `bun run verify:config-example`, `bun run typecheck`, `bun run test:fast`, `bun run test:env`, `bun run build`, `bun run test:smoke:dist`, `bun run docs:test`, and `bun run docs:build`.
