   MGNTION — RESPONSIVE SYSTEM

   Eight tiers, each designed rather than interpolated. The rule throughout:
   a handheld gets FEWER things at FULL size, never everything at reduced size.

     xs   320-375   small phones      one column, stanza hero, 44px targets
     sm   376-429   standard phones   more air, larger display type
     md   430-599   large phones      two-up grids return
     ts   600-833   small tablets     nav returns, plates go 16:10
     tl   834-1023  large tablets     two-column argument, desktop rhythm
     lap  1024-1439 laptops           full desktop composition
     dt   1440-1919 desktops          the reference design
     uw   1920+     ultrawide         wider measure, larger gutters, capped text

   Loaded last so it wins on equal specificity.
