 Media uploads everywhere use the image icon buttons (pasting into the editor works too). The article, banner and site-settings pens are shorthands that open the shell on the matching tab; once open, clicking a pen switches tabs (and retargets the editors to the current page) instead of closing/remounting. The close button in the tab bar closes the shell (Escape too); tabs have no close buttons of their own. Closing only HIDES the shell — the Vue app stays mounted, so page-editor state (unsaved text included) survives until a real page reload; saving there is explicit (Ctrl+S) and refreshes the page regions in place. Admin panels never reload the page.

+In-place page re-rendering shared by the banner/site/structure tabs lives in `swapdoc.js` (`runScripts`/`loadPlain`: fetch a page, swap the dynamic regions, replaceState). It also exports `dropPageCache`, which the editor tabs call after any save that can alter the rendered HTML of other pages (theme, headings, structure, banners, site brand/CSS, favicon).

-Everything saves immediately as you edit (brand/title/CSS debounced, slug on commit since it renames the path), theme change swaps the stylesheet in place, tree rows navigate in place without transitions when focused, and the front page is a root-only row whose empty slug is editable like any other.
+Everything saves immediately as you edit (brand/title/CSS debounced, slug on commit since it renames the path), theme change swaps the stylesheet in place, tree rows navigate in place without transitions when focused, and the front page is a root-only row whose empty slug is editable like any other. Saves that can affect other pages drop the prefetch cache; the cache is rebuilt when the editor panel closes so navigation stays instant.
 
 Every non-empty list (and the root) ends with a non-draggable plus footer row (vuedraggable `#footer` slot): clicking it starts a new pending page at that level (its slug placeholder shows the slug derived live from the title being typed), and while dragging it is the list's "end of list" drop target. Committing a pending page PUTs it with empty markdown (creates an empty page that renders with its title — saving never deletes; deletion is the page editor's explicit choice: saving trimmed-empty text issues a REST DELETE), then switches to the page editor tab for the actual writing.

 It first probes `GET /auth/api/settings` to detect whether Paskia SSO is available, then `GET /_api/settings` to learn the current session's admin status. The same reverse proxy that gates `/_api` returns 401 for anonymous users, 403 for users without the admin permission, and 200 for admins. When Paskia is detected, a login link (anonymous) or profile link (logged in) is shown in the banner corner; both are plain `<a href="/auth/">` links (Paskia does not support being iframed, so we navigate normally), and a `pageshow` handler re-probes auth when history navigation restores a cached page. Admins also get the page/banner edit pens and a site-settings pen, plus a `modulepreload` warm-up of the editor bundle (the hashed asset is immutable, so it costs nothing). If no Paskia SSO is detected (dev/no proxy), editing is left open. Pages themselves render identically for everyone; the real gate is the auth proxy in front of all of `/_api`.
