 ## Editing
 
 - 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.

 - `BannerEditor.vue` — per-page banner HTML + banner design selector, previewed into `#page-banner`.
 - `SiteEditor.vue` — site brand + optional custom brand HTML with image/video upload + theme selector + font picker + favicon upload — clicking the preview tile picks a new one — + site-wide custom CSS, CSS injected into `<head id="pagerite-user">`.
