   MOBILE OS TEXT SIZE
   Opt into iOS/iPadOS dynamic text-size preference. Setting
   font: -apple-system-body on html makes the root font-size track the
   OS Accessibility → Larger Text slider in Safari and Chrome on iOS.
   Firefox already honors OS text-size natively; no extra CSS needed.

   Desktop Safari also recognises -apple-system-body but maps it to the
   macOS UI body size (≈13 px). The @supports guard below resets the
   root font-size to 100% (browser default, 16 px) on Desktop Safari
   only: -webkit-touch-callout is iOS-only, so the NOT condition is true
   only on macOS Safari.
