Two analytics corrections verified against the production capture:

- pagerite.js suppressed pings with fr == '/_a', but fetch-navigation
  away from the analytics page had already GET-ed the target without the
  preload header; the orphaned pending hit then flushed to the crawler
  list, classifying a real user as a crawler. Navigations away from /_a
  now ping normally (the server rejects /_a as a target regardless, and
  admin noise is already handled by hide=1).

- _remove_visit only reversed the visit's creation counts, leaving
  views/transitions from later pings behind as orphans on the graph with
  no matching row in the visitor table. An in-memory per-visit count log
  now tracks every count event, so an admin hide=1 scrub reverses the
  visit completely.

Preview renders server-side per keystroke (no debouncing) straight into the visible article's heading and body.
   - **Site mode** — the 🖊️ on the banner opens a panel with the site **brand** (applied to the header live), a **theme** selector (swapping the theme stylesheet in place), **font** picks (heading/body/brand — stored as plain `:root` rows inside the custom CSS, referencing the base stylesheet's per-family font variables), a **site-wide custom CSS** field (injected into `<style id="pagerite-user">` in the live page head and swapped during fetch-navigation), the page's **banner design** selector (inherit / none / any design found on disk, inherited by children), the page's **banner HTML** field (supplementing the design, previewed into the real banner region, so you see exactly which banner you're editing) and the **structure tree**. Everything saves immediately as you edit — no save button, no edit mode.
 - Clicking a pen again closes the editor (without saving; a dirty preview reloads the page). The pens are `<button>`s wired up by `pagerite.js` — editing is an action, not a navigation. The editor's WebSocket **reconnects automatically** with local text and pending saves preserved. (All users are trusted authors for now; access control later with SSO.)
 - **CodeMirror 6** for Markdown editing (no WYSIWYG), title/published controls. Images can be pasted straight into the editor or chosen via a file input: they upload to the content store (`PUT /_api/files/...`) and insert `![alt](/_f/hash.ext)` at the cursor.

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). Placeholder texts are reserved for showing the actual default in effect when a field is left empty (e.g. the pending row's slug derived from its title); labels and help are real elements or tooltips, never placeholders.
+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). Dropping the cache while editing avoids re-fetching every page immediately; the public runtime re-preloads visible links once the editor panel closes.
 
 ## Saving behavior
 
-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.

+Public page entry; runs fetch-navigation (backed by an in-memory page cache: every visible internal link is fetched once at load and clicks are then served from JS with no fetch — the current page itself is not refetched, it enters the cache when navigated to — and the editors' `loadPlain` keeps the cache current via a `pagerite:page-fetched` event; articles are `cache-control: no-cache` on the wire). Editors can drop the entire cache with the `pagerite:drop-page-cache` event when site-wide or page changes (theme, headings, structure, banners, etc.) invalidate the cached HTML of other pages; `main.js` triggers a fresh `pagerite:preload-pages` pass when the editor panel closes so navigation is fast again. Navigation that starts while the editor is open bypasses the cache and fetches the target page on demand. Also runs scroll-reveal, OverlayScrollbars on `document.body` (floating, auto-hiding scrollbars that never reserve layout space or shift the page when appearing; native scroll APIs like `window.scrollTo` keep working; themed via the `--os-*` variables in pagerite.css), brand shrink-to-fit (the themed size is the maximum; JS reduces the font-size so a long brand or narrow viewport still fits one line), nav condense-to-fit (the top nav stays on one row: link gaps shrink first, then the side padding, then the font size; `flex-wrap: wrap` remains the no-JS fallback), code copy buttons, and the auth check.

+Asset wiring differs by mode. In dev the backend links the Vite dev-server URLs (`pagerite:editor-src`/`-css`/`pagerite:analytics-src` meta tags, `<link>` stylesheets) and Vite injects the entry CSS from JS for hot reloads. In production there are no pagerite meta tags: all page assets are inlined into the document — stylesheets as `<style>` elements in `<head>` (fixed order: base, theme, banner design, entry sheets, custom CSS last), module scripts as inline `<script>`s at the end of the body (relative chunk imports are rewritten to absolute `/_assets/` paths) — and the on-demand bundles' URLs ride in a `<script type="application/json" id="pagerite-assets">` config. The editor bundle always stays external, imported on demand when a pen is opened. Every stylesheet element carries a stable id so fetch-navigation and the site editor can sync `<head>` positionally across swaps (the analytics sheet exists on `/_a` only and is added/removed as you navigate). The analytics entry is inlined into the `/_a` page itself; pagerite.js re-creates that script element after fetch-navigating there (inline scripts don't execute on a DOM swap) and calls the module's exposed unmount before swapping away.
