/* ── MARCHIO: Mayhem Fitness ────────────────────────────────────────────────
   Giallo e nero presi dal logo (il giallo e' campionato dall'immagine:
   #f0c040). Tre famiglie di colore tenute SEPARATE di proposito:
     --brand  = marchio e azioni (bottoni, fuoco, sottolineature)
     --danger = errori e "pieno"          } significato, NON estetica:
     --ok     = conferme e "disponibile"  } non seguono il marchio
   Prima esisteva un solo `--red` che faceva sia da marchio sia da errore:
   ridipingendolo di giallo, i messaggi d'errore sarebbero diventati gialli. */
