Collapsing hid the sidebar entirely, and the toggle had moved into .menu-head
while the hide rule still targeted direct children of .sidebar-nav — so the head
went, taking the toggle with it, and there was no way to reopen the menu.
Collapsed is now a 52px icon rail rather than a disappearance: the mark, the
toggle, search and the account avatar stay reachable in place, so nothing has to
be floated over the content and there is always a way back. The assistant rail
collapses to the same strip.
Scrolling. The workspace list in the assistant rail had no overflow rule, so its
list of every app tab ran off the bottom and scrolling only appeared once you
left for the app. In the app sidebar the opposite: the whole sidebar scrolled, so
the account card scrolled away with the list and Settings and Log out became
something to hunt for. Both now scroll only the list, with the head and the
account card pinned.
The toggle was also being styled twice — as a head-row icon button and by its own
older rule with a different size and margin. It is now only the behavioural hook
that flips the icon.
Brand is PedAI, which is short enough to sit in the head row without squeezing
the controls; the collapsed rail shows the mark alone.
The reachability test now walks the toggle's real ancestor chain and fails if any
collapse rule hides a branch it sits on, rather than asserting one rule's text —
this class of bug has broken twice by moving the toggle deeper.
