* fix(docs): unbreak ascii-guard lint on github-pr-review-agent diagram
The intro diagram used 4 side-by-side boxes in one row. ascii-guard can't
parse that layout — it reads the whole thing as one 80-wide outer box and
flags the inner box borders at columns 17/39/60 as 'extra characters after
right border'. Per the ascii-guard-lint-fixing skill, the only fix is to
merge into a single outer box.
Rewritten as one 69-char outer box with four labeled regions separated by
arrows. Same semantic content, lint-clean.
Was blocking docs-site-checks CI as 'action_required' across multiple PRs
(see e.g. run 24661820677).
* fix(docs): backtick-wrap `<1%` to avoid MDX JSX parse error
Docusaurus MDX parses `<1%` as the start of a JSX tag, but `1` isn't a
valid tag-name start so compilation fails with 'Unexpected character `1`
(U+0031) before name'. Wrap in backticks so MDX treats it as literal code
text.
Found by running Build Docusaurus step on the PR that unblocked the
ascii-guard step; full docs tree scanned for other `<digit>` patterns
outside backticks/fences, only this one was unsafe.
