Website polish and route fixes
A compact cleanup release: sharper resource links, safer redirects, better archive coverage and small route fixes around the new content model.
This release collects smaller fixes that make the public site easier to navigate after the content-model changes.
Most of the work is invisible when it is working: old URLs should land somewhere useful, resource pages should point to the right surface and archive files should reflect the pages that exist.
Fixes
Old placeholder blog slugs now redirect to the closest launch-slate article.
Resources points readers to the Blog as the editorial archive instead of sending them to a thin list.
Blog and changelog archive URLs are listed for crawlers and feed readers.
Blog and Changelog are searchable from the command palette.
