   mobile.css — phone polish layer for the .studio-* shell.

   Loaded LAST in index.html so it wins the cascade over the base
   mobile rules in r2-tokens.css. Everything here targets the shell
   the app actually renders (.studio-shell / .studio-main /
   .studio-mobile-tabs / .modal-scrim). An earlier version of this file
   styled a previous prototype shell (.dirA-*) that no longer renders,
   so none of it applied — that's why mobile nav, modals, and overflow
   were unstyled. Breakpoint matches the shell flip at 860px.
