   In-site accessibility choices, applied as data attributes on <html> before
   first paint (see the inline script in index.html). Each block mirrors the
   OS-level media query the site already honours, so choosing "motion off"
   here does exactly what the OS setting does, and low-stimulation goes one
   step further.

     data-motion="reduce"   every prefers-reduced-motion rule, forced
     data-stim="low"        no ambient field, no swirl, no grain, no marquee,
                            no tilt, no sheen, no gradient type, solid colour
     data-font="dyslexia"   Lexend, wider spacing, longer leading
     data-text="large"      root font-size up 18%
