/* Contrasto WCAG 2.2 SC 1.4.3 (2026-08-10): testo bianco sul RIEMPIMENTO del
   bottone "Accedi" (gradiente 135deg `--mido-red` -> `--mido-red-dark`,
   dichiarato in `.mido-primary-btn` di login-modern-assets.css) misurava
   4.33:1 nel punto più chiaro del gradiente (var(--mido-red) puro, #E72D3F)
   — sotto soglia: 17px/700 non raggiunge la soglia "large text" di WCAG
   (serve >=18.66px bold), quindi vale 4.5:1 pieno, non 3:1.
   Calcolo (luminanza relativa, sRGB->lineare, formula WCAG 1.4.3):
     #E72D3F -> R_lin .7995  G_lin .0262  B_lin .0498 -> L = .1923
     contrasto = (1.00+.05)/(.1923+.05) = 4.33:1   (< 4.5 -> FALLISCE)
   Fix, stessa logica del token `--primary-fill` del theme MiDo: l'ACCENTO
   `--mido-red` resta l'accento ovunque nella pagina (icona hero, sottolineatura
   editoriale, badge numerati — nessuno di questi è dentro questo bottone), e
   solo il RIEMPIMENTO del bottone si scurisce. Le custom property CSS si
   risolvono per cascata sull'ELEMENTO che le consuma, non per foglio di
   provenienza: qui si ridichiara localmente la stessa var che il gradiente di
   `.mido-primary-btn` legge (login-modern-assets.css, file diverso) — il fill
   scurisce senza toccare né l'accento globale né quel file.
     #DC192D -> R_lin .7157  G_lin .0097  B_lin .0262 -> L = .1610
     contrasto = 1.05/.2110 = 4.98:1   (>= 4.6 richiesto, margine incluso)
   Lo stop scuro (`--mido-red-dark` #C91F31, INVARIATO) è già a 5.64:1: non
   serve toccarlo. Ed è anche perché l'hover resta a norma senza altre
   modifiche — `.mido-primary-btn:hover` (login-modern-assets.css) cambia solo
   `box-shadow`/`transform`, mai il `background`. */
