Pull request overview

Adds an embedded walkthrough video to the Tokens reference docs showing how to mint GITHUB_COPILOT_TOKEN for org-owned repositories.

Changes:

• Inserts an HTML <video> embed (with caption) under the org-owned repository PAT instructions.
• Adds additional spacing around the “Setup” section.

• The <video> element is missing the accessibility/performance attributes used elsewhere in the docs (e.g., preload="metadata" and an aria-label derived from the caption). Also consider using a richer fallback (e.g., a paragraph with a direct download link) so non-video-capable browsers still have a usable path.

    Your browser does not support the video tag.
  </video>

• The poster path points to /gh-aw/videos/create-pat-org-copilot.png, but there doesn’t appear to be a corresponding docs/public/videos/create-pat-org-copilot.png asset. Either add the poster image or adjust/remove the poster attribute to avoid a broken request.

There are two extra blank lines here that add unnecessary vertical space before the Setup section. Please remove the redundant empty lines to keep the docs formatting consistent.

Suggested change

[Copilot]

This video block isn’t using the existing video styling structure/classes (e.g., gh-aw-video-container + gh-aw-video-element) and instead relies on inline styles. Consider matching the structure used by docs/src/components/Video.astro so you get consistent border radius, aspect-ratio handling, and theming without inline CSS.
