   next to native; day-dom's ramp applies the SAME factor.
     - Desktop keeps a FIXED base (1rem = the browser's font-size preference), so Safari and Chrome
       on the same Mac render identically and nothing shrinks to the bare 13px system size.
     - Touch devices anchor `html` to `-apple-system-body`, whose value IS iOS Dynamic Type: every
