Editor panel layout fixes, use body scroll and bidirectional sync with editor.

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.

 - Editing happens **in place**, in two modes opened by two pens:
-  - **Page mode** — the 🖊️ next to a page's heading (including 404s, which is how new pages start) opens a CodeMirror Markdown editor docked to the left of the article: the host sits inside `#content` (below the banner, never over the footer), the content shifts right and the sidebar hides while editing. Preview renders server-side per keystroke (no debouncing) straight into the visible article's heading and body.
+  - **Page mode** — the 🖊️ next to a page's heading (including 404s, which is how new pages start) opens a CodeMirror Markdown editor docked to the left of the article: the panel is fixed to the viewport's left edge (its top tracks the banner's bottom until the banner scrolls away), the content shifts right and the sidebar hides while editing. 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.
