Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 41s
dom-parse-html returned body.childNodes — a NodeList, not a Node — so the client SX render did appendChild(NodeList) and threw "Argument 1 does not implement interface Node", silently dropping every raw! HTML block (e.g. a post's <article> body). It surfaced only now because the blog renders fragments client-side (text/sx) since this session; before, fragments were server HTML so sx-render never ran on raw!. The error is caught/non-fatal, and the spa-check suite only asserted the footer + URL behaviour, so it passed through a dropped post body. - dom-parse-html now returns a DocumentFragment (moves the parsed nodes in): a real Node, appendChild-able as one unit, and queryable — which also fixes the already-broken hs-htmx callers that did (dom-query doc ...) / (dom-first-child doc) on what was a NodeList. - spa-check: assert #content article is visible after a boosted nav, so a dropped post body fails the suite (closes the test gap). - .sxbc regenerated; bundle dom.sx synced to canonical web/lib/dom.sx. Verified: spa-check 4/4 (incl. the new article assertion).
