The nav labels (New session, Skills, …) and the ⌘N hint were gated on a
viewport breakpoint (max-[46.25rem]:hidden), so shrinking the window hid
them even when the sidebar itself was wide — including in the hover-reveal
overlay. Drop the gate; the label already truncates (min-w-0 flex-1) so it
ellipsizes gracefully in a narrow rail, and contentVisible already hides it
when collapsed to the icon rail.
