Reduce #brand to actual size, avoid clicks on empty banner space touching it.

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.

In production the rendered bodies are cached in an LRU keyed by everything the output depends on — page kind, path, the site origin (social meta), encoding, and `data.version`, which bumps on every content/settings change and so transparently invalidates the whole cache. The cache is bypassed in dev, where theme/design CSS is re-read from disk per request.

+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.
