   Mobile Baseline — audit responsive 2026-04-24.
   Regole globali per eliminare problemi mobile trasversali senza dover

   1) Input font-size 16px — previene il zoom iOS automatico su tap.
      Apple Safari iOS zooma qualsiasi input con font-size < 16px: UX
      pessima perche' sposta il viewport. Alta specificita' (html body + attr
      selector) per vincere il cascade rispetto alle regole inline locali.

   2) Tap target min 44x44px su dispositivi touch — standard Apple HIG +
      WCAG 2.5.5 (AAA). Media query '(hover: none) and (pointer: coarse)'
      isola solo mouse-less touch: desktop con touchscreen ibrido NON viene
      toccato. min-height non altera il layout se il padding gia' basta.

   3) Container padding adaptive — le pagine usano 20-32px di padding
      orizzontale fisso. Su <=768px (tablet portrait) ridotto a 16px; su
      <=480px (phone) a 12px. Riprende spazio per il contenuto senza rompere
      il layout desktop.
