/* ============================================================================
   CuraFauna — shared responsive layer
   ----------------------------------------------------------------------------
   Every app page carries its own copy of the base stylesheet inline. This file
   is linked AFTER that inline <style> on each page, so these rules win on equal
   specificity and one file controls the whole app's small-screen behaviour.

   Pairs with mobile-nav.js, which injects the menu button and backdrop and
   toggles .cf-nav-open on <body>.

   Breakpoints
     <= 1080px  tablet landscape — 4-up KPI rows go 2-up, side column stacks
     <=  900px  sidebar goes off-canvas behind a menu button
     <=  620px  phone — single column everywhere, secondary table columns hidden
