   Media queries measure the REAL viewport, but content above the
   zoom cutoff renders 1.25x (tokens.css: --zoom = 1.25, dropping
   to 1 at ≤1024px). So breakpoints targeting zoomed screens are
   multiplied by 1.25:
     1475 real = 1180 effective · 1280 real = 1024 effective
     1125 real =  900 effective (pages.css)
   Breakpoints ≤1024 real (900, 640) run unzoomed = truthful.
