   Meditecha · css/app.css  (Etapa B)
   Stilurile proprii aplicației, scrise pe tokenii medtool.ro (tokens.css)
   și în stratul `app` (declarat în tokens.css: legacy < tokens < components < app).
   ------------------------------------------------------------
   Reguli:
     - niciun hex în componente: doar var(--mt-…). Excepție marcată (secțiunea 13):
       fundalul gri al cititorului PDF, independent de temă, ca în orice vizualizator PDF.
     - mobile-first: regulile de bază sunt cele de telefon; desktopul (≥761px) e excepția.
     - ținte de atingere ≥ 44px pe telefon (--mt-tap); pe desktop densitatea coboară.
     - 100dvh peste tot unde monolitul avea 100vh.
   Numele claselor sunt cele din HTML/JS — JS-ul nu a fost atins pentru stiluri.
