/* ══════════════════════════════════════════════════════════════════════
   CollabHub — Responsive / Mobile layer
   ----------------------------------------------------------------------
   Hand-authored plain CSS, loaded AFTER tailwind.css (survives rebuilds).
   Targets: iPhone 17 / 16 / Pro Max / SE · Android flagship + small · iPad
            & Android tablets · both portrait & landscape.

   Strategy
     • < 1024px  → off-canvas drawer sidebar + hamburger (phones & tablet portrait)
     • >= 1024px → original fixed sidebar untouched (desktop / tablet landscape)
     • Touch targets >= 44px · notch / dynamic-island safe-area · fluid spacing
     • Tables keep their columns and scroll horizontally (auto-wrapped in JS)
