   Desktop viewport scaling — each unit fills ~one screen.

   Everything below is written as clamp(default, vh/vw-based, cap), so the
   low end of every clamp is exactly the fixed default above (used as-is
   below this breakpoint, and as the floor on a short/cramped desktop
   window), the middle term ties the value to viewport size, and the top
   end caps it so nothing balloons on a huge or ultra-tall monitor.

   Gated to min-width so narrow/mobile layouts (designed separately later)
   are completely untouched.
