 Since 7.0 enabled view transitions in wp-admin (#64470, [10699]),
 navigating between admin screens crossfades the entire admin sidebar
 into itself, even when its markup is identical between the two pages.

 `src/wp-admin/css/view-transitions.css` gives each top-level menu item
 a stable `view-transition-name`, but `#adminmenu` itself does not — so
 the whole sidebar falls into the default root snapshot and crossfades
 on every navigation.

 Screencast: https://github.com/user-attachments/assets/7a48ae52-70d7-47ee-
 95e0-aec80463dcde

 == Steps to reproduce ==

 1. Run trunk in Chrome.
 2. Log in to wp-admin.
 3. Click between two screens whose sidebars are nearly identical (e.g.
 Dashboard → Posts → Pages).

 == Expected ==

 Sidebar stays visually stable across the navigation — nothing in it has
 changed.

 == Actual ==

 The whole sidebar crossfades between two identical snapshots.

 == Notes ==

 Claude claims a likely fix is to give `#adminmenu` (and possibly
 `#adminmenuwrap`)
 its own `view-transition-name` so it's treated as a single persistent
 element
 across navigations rather than part of the default root snapshot. To be
 verified.
