/* ================================================================
   Flourish Mobile Shell
   ----------------------------------------------------------------
   Adds three things, all hidden on desktop, all activated below
   1024px or on touch-first devices:
     1. Hamburger button in the top bar
     2. Slide-in drawer that wraps the existing .sidebar
     3. Bottom tab bar (≤640px only)
   The desktop sidebar stays exactly as-is.
