Summaries render as plain text in a single <p> (ContentSection.astro,
HackCard.astro), so markdown emphasis, [label](url) links, [[wikilinks]],
callouts, headings and bare URLs all showed literally on the site. All 87
affected summaries rewritten as clean prose upstream in the vault.
Counts unchanged at 411, so no fixture updates. Verified: npm run check
(0 errors, vitest 9/9), npm run build (486 pages), CI=1 npm run test:ui (8/8),
plus a scan of all 411 built pages' rendered Summary paragraphs showing zero
markdown residue.
