The phone shell no longer builds its tab bar and backdrop or writes their
aria-expanded, aria-hidden and hidden state: it publishes its tabs,
whether it is on and the open sheet to the gev-display store, and a new
PhoneTabBar component in the dock teleports them to the end of the page
from the first publish until the shell is destroyed, so they still follow
the scene's credits. The shell takes tab and backdrop clicks from the
document and returns focus to a tab once the tab bar shows it closed; a
reopen or destroy cancels a pending return.
The Cyber accordion now applies to both sidebars and every HUD layout:
opening a side panel collapses its peers, the layout normalizes restored
state to one owner, and collapsed panels are hidden on desktop. Phones keep
showing several panels per sheet.
At 720px and narrower the globe stays full screen and a bottom tab bar (Layers,
Cameras, Context, Search, More) opens one bottom sheet at a time, presenting the
existing rail and dock panels in place. Sheets borrow panels without persisting
or sharing them and put back what they changed. Cockpit, recording and clean
view close the sheet; scene playback keeps STOP reachable. Focus moves into the
sheet and back to its tab, the required attribution stays visible above the
voice control and any sheet, and the page uses safe-area insets. Wider
viewports are unchanged.
