/* ═══════════════════════════════════════════════════════════════════
   Regolo DPI — foglio di stile unico.

   È copiato dal prototipo /app/regolo-app.html senza ritoccarlo: il
   prototipo è stato guardato, discusso e collaudato con queste misure
   e questi colori, e rifarle "meglio" adesso significherebbe buttare
   via l'unica parte del progetto già validata da occhi umani.

   Sta in un file esterno e non dentro <style> per due motivi: la CSP
   servita da Cloudflare è più contenta di style-src 'self', e ogni
   schermata scritta da un agente diverso eredita le stesse classi
   senza doverle ricopiare.

   Le classi sono il vocabolario condiviso fra tutte le schermate:
   .card .kpi .pill .tw .note .btn .field .chip .dl .mod .strip.
   Prima di inventarne una nuova, cercare qui.
