/* ============================================================
   Phones and tablets. Loaded last (after app.css, chilledai.css, round2.css).
   Desktop (> 1100px wide, mouse) is unchanged: every rule here sits in a media query,
   except the menu button / drawer elements that are hidden on desktop.
   Breakpoints: <= 1100px iPad portrait (narrow, collapsible sidebar);
                <= 760px phones (top bar + slide-in drawer); <= 640px tables stack into cards.
   Touch devices (pointer: coarse) get 44px tap targets and 16px form text (stops iOS zoom).
