Generate or refresh Avo v4 docs screenshots (and animated GIFs) from `<Image prompt>` placeholders. Use when the user asks to add/create/refresh screenshots or GIFs for a docs page, a section, or all of docs/4.0 — anywhere a `<Image prompt="…">` placeholder needs to become a real light+dark asset. A placeholder with `kind="gif"` becomes an animated GIF; otherwise a static PNG. Resolves each placeholder by capturing the live Avo demo app, verifies it against the framing rules, rewrites the tag, and stops with everything unstaged (no commit/push/PR).
Write and edit Avo documentation pages following this repo's guide + reference (API) two-page model. Use whenever you're adding or editing a docs page under docs/ — documenting an Avo feature or config option, writing a how-to guide, building or updating an `-api.md` reference page, adding `<Option>` blocks, setting docs frontmatter (license, outline, api_docs, guide), cross-linking a guide to its API reference, or deciding whether a feature needs one page or two. Also use when the request mentions "document this feature", "write the docs for", "Avo docs", "the API page", "the reference page", "<Option>", or "config.<something>" in a documentation context. Reach for it even when the user just says "add docs for X" without naming the format — getting the structure, frontmatter, and cross-links right is the whole point.
