   Cross-page navigation — index / cambrian / privacy share this

   should read as a content change, not a reload. Browsers with
   the View Transitions API (Chrome/Edge, Safari 18+) get a short
   eased cross-fade of the page body; the background field holds
   still underneath it. Everywhere else the navigation is instant
   with no flash — nothing to fall back from.
