- Force font-size:16px !important on Styles-sheet/topbar/Sitesmith inputs
inside the mobile media query so inline 12px/14px styles stop triggering
iOS zoom-on-focus.
- Lift sheet-open + Templates/Head Code modal-open state out of private
useState into a shared MobileChromeContext (EditorShell), so Phase B can
open/close sheets from outside MobilePanelBar.
- Add an explicit z-index layer scale, portal TemplateModal to
document.body (was trapped under the tab bar inside .topbar's stacking
context), align Sitesmith to the same --z-modal layer, and make opening
a sheet close any open modal. Also fix modal backdrops swallowing tab
bar taps (mirrors the sheet backdrop's existing tab-bar cutout).
- Drop BottomSheet's incorrect aria-modal; mobile-aware AssetsPanel empty
state copy.
- Tests: useIsMobile (matchMedia mock incl. legacy fallback + cleanup),
MobileChromeContext invariants (one sheet open, sheet closes modals),
MobilePanelBar wiring.
