   hidden-attribute fix for the two shells

   regardless of specificity, that flex rule would otherwise defeat the
   `hidden` attribute entirely. These two rules make `hidden` win back by
   matching on the attribute at equal-or-higher specificity.

   what a class rule elsewhere sets `display` to. A static audit found six
   elements across wallet forms, the Buy Electricity token panel, and the
   scanner fallback/confirm panels that were ALWAYS visible despite being
   marked hidden, because a class-based `display` rule (same author
   origin, equal specificity) was declared after `[hidden]` in the
   cascade and simply overrode it. The per-element overrides above predate
   this and are now redundant but harmless. This one rule covers every

   Responsive: desktop layout

   Below ~880px this file is untouched — that's the exact mobile layout
   it's always been, phone or otherwise. Above that, the app stops being
   a phone-width column stretched into empty space on a wide screen and
   becomes an actual desktop layout:
     - the app frame widens and gets a subtle card treatment on the page
     - the tab bar moves from a bottom mobile tab bar to a top nav, via
       explicit flex `order` on the three #app children — no DOM/JS
       change, so mobile markup and behavior stay identical
     - content settles into a comfortable reading width instead of
       stretching edge to edge across the whole frame
     - sheet overlays (Bill Centre, Link a Meter, Manage Admins) stop
       sliding up as a mobile bottom sheet and become a centered dialog
