📝 Summary

Summary by CodeRabbit

• Documentation
  • Added a centered Dash logo beneath the README title, displayed at 840 pixels wide with descriptive alternative text.
  • Added documentation describing the artwork’s history, approved use, and rights limitations, along with a receipt recording its generation and review details.
• Chores
  • Excluded brand assets and the mascot banner and its receipt from exported archives.

Walkthrough

The README displays a centered Dash logo at 840 pixels wide. Brand documentation and a JSON receipt record the image’s provenance, publication authorization, and rights statements. Git export excludes the brand directory and two documentation files.

The brand README and JSON receipt document its provenance, publication authorization, and rights statements. Git export excludes /assets/brand/ and the two listed documentation files.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Other

Merge Risk: ⚪ Minimal · up to f41b0

Before / after behavior

• observed — Modified behavior in README.md: Added a centered logo image with descriptive alternative text and a width of 840 pixels.
• observed — Modified behavior in assets/brand/README.md: Identifies the contextual illustration and its local path, explains the root README’s immutable-commit URL versus the documentation path, and captions the clock scene.
• observed — Modified behavior in assets/brand/README.md: Records the superseded welcome-copy history and the commits used for the current clock scene, describes its visual comparison with the approved welcome master, and links the generation receipt and canonical brand kit.
• observed — Modified behavior in assets/brand/README.md: Records the maintainer’s dated authorization for public README and documentation use, states that historical source-art rights are unrecorded, and disclaims an independent asset license or extension of the software license to the image.

_{A rabbit found a banner bright
And placed it neatly in the README
Its history sits beside the art
While export leaves the source apart
Then hops away beneath the clock!}
