The admin drew its own copy of the rail, with a logo and only the app
links, next to a sidebar that signed out from its footer. It now renders
the webmail's NavigationRail (desktop and phone), which needs the
translation, theme and tour providers under /admin, so the admin layout
loads the message catalog itself; the rail marks Admin as the current
app for password admins too. The sidebar footer carries the admin
session links and the same about footer as the settings. Plugin and
theme rows and the detail header show the extension's icon from the
directory listing instead of a generic one, and a plugin's own settings
move to the bottom of its page, after availability, permissions and
versions.
The old panel kept its active tab in a store, so every page sat at
/admin, the sidebar duplicated the webmail rail by hand, and each page
was a stack of boxed cards with their own save buttons. Plugin settings
were only reachable through a gear icon in a row of five.
- one catch-all route for the whole panel; pages switch through
history.pushState, so `/admin/plugins/<id>`, the back button, bookmarks
and connector links all work without a route transition
- sidebar laid out like the user settings: back to mail, search over
pages and their sections, two group headings, change password and
sign out at the bottom; the phone shows a list, then the page
- pages use SettingsSection rows instead of nested cards, with one page
header, one flash message and one save bar at the bottom (Discard,
Save, Ctrl+S); the unsaved-changes prompt still guards leaving
- plugins and themes are lists of rows with a toggle each; a row opens
the extension's own page with its settings, force-on, permissions,
kept versions and removal
- overview shows stat tiles, server facts and recent activity
- old `/admin?tab=x` links redirect; the tab store is gone and the
connector registry resolves admin links to the page URL
- `NEXT_TURBOPACK_ROOT` overrides the Turbopack root so `next dev` runs
from a worktree with a junctioned node_modules
