[sourcehawk]

Added logo image to README for better visual appeal.

Pull request overview

Adds a centered logo to the project README to improve the repository’s visual presentation near the top-of-page introduction.

Changes:

• Embedded a logo image in README.md using an HTML <img> tag and a GitHub user-attachments URL.

[Copilot]

The logo is referenced via a github.com/user-attachments/assets/... URL. These attachment URLs aren’t a stable, versioned project asset and can break or become inaccessible; consider committing the logo into the repo (e.g., docs/assets/logo.png or .github/assets/) and referencing it via a relative path or raw GitHub URL so it’s durable and works offline/forked copies.

Suggested change

	<img width="400" height="400" alt="OCF Logo" src="https://github.com/user-attachments/assets/ac8162e7-5963-4284-a590-5a9215090103" />
	<img width="400" height="400" alt="OCF Logo" src="docs/assets/logo.png" />

[Copilot]

The image hard-codes both width and height to 400px, which can distort the logo if the source isn’t perfectly square and doesn’t adapt well on small screens. Prefer specifying only one dimension (or using style="max-width: ...; height: auto") so the aspect ratio is preserved and the README remains responsive.

	<img width="400" height="400" alt="OCF Logo" src="https://github.com/user-attachments/assets/ac8162e7-5963-4284-a590-5a9215090103" />
	<img alt="OCF Logo" src="https://github.com/user-attachments/assets/ac8162e7-5963-4284-a590-5a9215090103" style="max-width: 400px; width: 100%; height: auto;" />

[Copilot]

This adds raw HTML (<p align=...><img .../>) to the README; the rest of the repo’s markdown docs appear to avoid embedded HTML. Consider using standard Markdown image syntax instead (and center it only if necessary) to improve portability across renderers (e.g., pkg.go.dev) and keep documentation style consistent.
