/* ============================================================
   Creator Cache™ — mobile & installed-app layer

   Loaded last, so it wins on equal specificity. Everything here
   is either phone-only (inside a max-width query) or safe at
   every size; the desktop layout is untouched.

   Three jobs:
     1. make a phone a first-class target, not a shrunk desktop
     2. behave like an app once installed (safe areas, no
        rubber-band, no accidental zoom, a real tab bar)
     3. keep hit targets at 44px, which is where most of the
        "it doesn't work on my phone" reports actually come from
