/* ============================================================
   FlashDex — phone layout

   Loaded last, so it wins. Most members open this on a phone, so
   below 900px the desktop rail is dropped entirely and replaced
   with the pattern people already know from every other app on
   their home screen: a fixed bottom tab bar, a compact sticky
   header carrying the one number they came to see, and a sheet
   for everything secondary.

   Sizing rules held throughout:
     · every tap target is at least 44px tall
     · nothing below 11px, ever
     · safe-area insets respected, so the tab bar clears the
       home indicator on a notched phone
     · content never scrolls sideways
   ============================================================ */

   attribute cannot be what keeps it off a desktop. Without an explicit
   default the unstyled header renders its logo at full page width. */
