Docs used to render as a clumsy link that navigated to a separate page. They
now render in place: build_gallery pre-renders each doc (markdown -> HTML,
plain text raw) and the gallery shows it inside a native <details open>
disclosure that spans the full grid width so prose has a readable measure.
The doc bar carries: a collapse chevron (the whole <details> summary toggles,
works with JS off), a full-page link (still reaches the standalone viewer), a
download link, and a session-close ✕. The ✕ needed stopPropagation +
preventDefault because it lives inside <summary> — otherwise its click would
toggle the disclosure instead of hiding the item. Close is JS (progressive
enhancement); collapse is native.
Two design points:
- Plain text is returned RAW from build_gallery and escaped by the template
inside <pre>. Pre-escaping in Python plus Jinja autoescape would
double-encode angle brackets; a test pins the single-escape.
- Inlining is bounded by DOC_MAX_BYTES. A doc over the limit keeps the old
link-out behaviour rather than being rendered into every index load; a test
covers the fallback.
The shared .markdown-body / .textview typography moved from doc.html's scoped
<style> into base.html so the inline body and the full-page view render
identically; doc.html keeps only its page-layout wrapper.
Updated the pre-existing test_gallery_links_docs_to_view: it asserted the old
link-out behaviour the operator asked to change, so it now asserts the inline
render plus the surviving full-page and download affordances. 61 pass.
Verified live: markdown renders with headings/table/blockquote/code, txt
preserves whitespace and single-escapes, collapse and ✕-close both work.
