/* =====================================================================
   Responsive strategy — TABLET IS THE TARGET DEVICE, not an edge case.
   Base table/panel/spacing rules above are already reasonably dense;
   everything below makes them DENSER for tablet/touch screens, using
   a combined signal that doesn't depend on any single unreliable
   check:
     - max-width: 1366px catches virtually every tablet in EITHER
       orientation (even a 12.9" iPad Pro landscape tops out around
       1366px CSS width) without depending on browser feature support.
     - (hover: none) and (pointer: coarse) catches genuine touch input
       as a second, independent signal, in case a specific tablet
       browser ever reports an unusually wide viewport.
     - The comma between them is CSS's OR — either condition alone is
       enough to trigger compact mode. A 14"+ laptop (mouse/trackpad,
       CSS width comfortably above 1366px) matches neither, so it's
       untouched — exactly the "laptop is fine" baseline being asked for.
