Important

• Merge feat: generate shared installation walkthroughs VPDPersonal#4 and verify its first successful Pages deployment before merging this PR.

Why

The GitHub installation recording is duplicated locally and has to be re-recorded when the package changes channels. Select shared generated media from the copyable install command so the illustrated stable/preview URL stays aligned automatically.

What

• Select shared WebP and PNG from the install command's channel.
• Preserve native numbered steps and the copyable URL.
• Remove the duplicated recording and manual re-recording warning.
• Keep the documentation site's interactive installation panel.

Start with: Website/scripts/github-readme.mjs, then Website/scripts/sync-readme.mjs and scripts/set-version.sh.

Before	After

Matching full-URL key frames in GitHub's Markdown styles. The shared picture has a static PNG fallback; the steps and copyable URL stay native text.

Narrow README layout

The existing table retains all three instructions and the copyable command without page overflow.

Verification

• Website tests → 102 passed, including stable/preview installation image selection.
• Repository script tests → 141 passed, including release-channel transitions and generated README checks.
• README synchronization and translation checks → passed.
• EN/RU production builds → passed; existing cqi minimizer warnings retained.
• Package, samples, versions, minimum Unity, contrast and skills checks → passed with existing contrast baselines.
• README local-path checks → 47 paths, 0 errors.
• GitHub Markdown API → picture, WebP source and PNG fallback retained.
• Actual GitHub Markdown styles → before/after at 1080px/375px, dark/light; decoded images, native steps, copyable URL, no overflow.
• Local feature recorder syntax and git diff --check → passed.
• No Unity test inputs changed; unity-quick is not needed.
