/* (1) Prima colonna schiacciata a 1-2 lettere per riga (foto utente, tabella
   della sifilide congenita in Infettive).

   Causa: `.teoria-accordion-body { word-break: break-word }`, scritto identico
   in 74 pagine di teoria. Quel valore e' deprecato e per specifica CSS equivale
   a `overflow-wrap: anywhere` — l'unica variante che entra nel calcolo della
   larghezza MINIMA. La larghezza minima di ogni cella diventa cosi' un singolo
   carattere, la proprieta' si eredita nelle celle e l'auto-layout ripartisce lo
   spazio in proporzione al solo contenuto massimo: la colonna di prosa si
   prende tutto, quella corta collassa. E siccome il minimo e' ~0, la tabella
   `display:block; overflow-x:auto` non ha mai bisogno di scorrere → nemmeno lo
   scorrimento la salva.

   Controprova: le pagine di teoria vecchia maniera (cardiologia, cute,
   ecocardio, ecopolmonare, emodinamica, genetica) NON hanno quella riga e le
   loro tabelle scorrono correttamente.

   Perche' basta questo e non serve `!important`: qui il valore e' dichiarato
   DIRETTAMENTE sulla cella, mentre la pagina lo dichiara sul contenitore. Un
   valore diretto batte sempre uno ereditato, a prescindere dall'ordine di
   caricamento e dalla specificita'.

   Volutamente NON si aggiunge `min-width` sulle celle ne' `hyphens:auto`: il
   primo gonfia le tabelle a 8-12 colonne dove una colonna contiene solo un
   numero o "Si/No", il secondo sillaba male sigle e nomi propri. Con
   `word-break: normal` la larghezza minima torna a essere la parola piu' lunga,
   che e' esattamente quel che serve; se dopo il rilascio qualche colonna
   risultasse ancora stretta, il minimo si aggiunge come secondo passo mirato. */

  word-break: normal;
  overflow-wrap: break-word;
}

/* (2) Prontuario farmaci: schema posologico tagliato sul bordo destro
   (foto utente, colonna "20 mg/kg/do..." troncata).

   Causa diversa dalla precedente: la tabella viene generata SENZA un
   contenitore scorrevole (`farmaci.html:759`), sta dentro `.drug-card`, che ha
   `overflow: hidden`, e la pagina impedisce lo scorrimento orizzontale con
   `html, body { overflow-x: hidden }`. Risultato: se le tre colonne non ci
   stanno, la parte eccedente viene semplicemente tagliata e non c'e' modo di
   raggiungerla.

   La tabella diventa qui un blocco che scorre per conto proprio — lo stesso
   schema gia' usato nelle pagine di teoria. La pagina dichiara per
   `.dosing-table` solo width, border-collapse e font-size: `display` e
   `overflow-x` non li tocca, quindi queste righe sopravvivono senza forzature. */
