## Embedding rules

- No account, token, or API key is involved. Every URL is a plain public image.
- Themes are baked into each asset because GitHub renders README images against the reader's OS preference, not the page. Publish both variants with an HTML `<picture>` element, or pick one explicitly with `theme=light` / `theme=dark`. There is no `theme=auto`.
- Published snippets are static. Motion is opt-in: add `animate=1` to an SVG URL, or use the `.gif` variant where one exists, because GitHub strips SVG animation from README images in several contexts.
- Keep the surrounding link and its `?ref=readme` parameter. Attribution lives on the link; the image URL stays plain so CDNs can cache it.
- Do not add cache-busting query parameters. Media is edge-cached for a few hours by design and refreshes on its own.
- Alt text is not optional. Say what the image shows, not "chart".
- A repository nobody has analyzed yet renders a placeholder frame and queues the work instead of failing. Load the page once, or wait a few minutes, and the real chart replaces it at the same URL.
