/* ── Casa Tasselli · stile "Studio" (12/10/2026) ─────────────────────────────────────────────────────────────
   Un foglio bianco con un binario nero di icone a sinistra: card pastello senza bordi, numeri in grassetto, un blocco nero
   in evidenza, niente vetro e niente nebbia. Si attiva con data-skin="studio"; il tema scuro ne dà la variante notturna.
   Le regole valgono solo con questo stile. */
