/* voice.css — Voice Practice e Voice Check.

   Uscito da `index.html` il 2026-09-20 (passo 1.1), dove il CSS era il 70%
   del file. ⚠️ L'ORDINE DEI `<link>` E' LA CASCATA: questi fogli sono stati
   tagliati dal foglio unico SENZA riordinare niente, e vanno caricati
   nell'ordine in cui `index.html` li elenca. Spostarne uno cambia quali
   regole vincono, e non alza nessun errore.

   Le regole 2, 3 e 12 di CLAUDE.md valgono qui come valevano prima:
   nessun colore fisso fuori dai temi, nessun valore modificabile nel CSS,
   e la guardia `[hidden]` non si tocca (sta in `base.css`). */

  /* job 8 (3rd collaudo): the "1 / 7" progress counter used to have its
     own .vc-counter rule here — smaller, unbolded, faded to 0.6 opacity —
     visibly different from Speed Match/Match Practice/Flash Card's own
     counters even though it's the exact same kind of information. Now
     shares .sr-counter (in `stile/speedmatch.css`) like Match Practice already
     did, instead of a fourth near-duplicate rule. */
