Problem and outcome

The demo page embedded the narrated walkthrough of version 2 inside a collapsed "Historical version 2 narrated tour" block. A narrated tour of version 3 is now published, so the page should show that one as the current tour.

• site/video.js embeds the new video; every "Watch on YouTube" and chapter link on site/demo.html points to it.
• The collapsed historical block becomes an open "Narrated tour" section.
• Chapters and transcript are rewritten for the new video (eight chapters, 2:17).
• Captions and poster are replaced under their existing file names.
• The music credit for the old soundtrack is removed together with its styles. The new video does not use that track.
• docs/webssh-3.md no longer describes the narrated video as historical.

The opt-in loading, the consent notice, the Content Security Policy and the privacy notice are unchanged.

Scope and links

Related issue/proposal: none, site content only.
Target milestone (if accepted into a release): none.

Validation

• Exact tested revision and checks/results: this commit. pytest tests/test_documentation_surface.py tests/test_public_product_surface.py tests/test_branding.py tests/test_repository_hygiene.py tests/test_license_consistency.py tests/test_ci_change_scope.py: 190 passed. scripts/check_repository_hygiene.py and scripts/check_license_consistency.py pass. The full suite was not run locally.
• Regression/acceptance coverage: test_demo_is_opt_in_and_has_local_preview_and_text_alternatives now expects the new video link, eight chapter times, the 2:17 caption and no "Historical" label.
• Compatibility, upgrade and security impact: none for the application. Site only; no new third-party hosts, and nothing loads from YouTube before the visitor opts in.
• Remaining deployment-specific checks or explicit limitations: the unbuilt page was loaded from a local static server (eight chapters, no link to the old video). The built and published site should be checked once after deployment, including loading the player.

Delivery

Merging implements the change; it does not publish a versioned release.
