   Singura exceptie e textul MIC continuu, care pe fundal deschis ar cobori la

   `text-accent-text` / `accent-text-d`), adica #CC3100 in light (5.02:1) si
   #FA3C00 in dark, unde problema nu exista.
   Locuri auditate individual care folosesc varianta AA-safe:
     .eyebrow (0.75rem), .bs-badge (0.66rem, doar culoarea de text),
     badge-urile de serviciu din cardurile de portofoliu (0.62rem),

     rolurile din grid-ul de echipa (text-sm), status-ul formularului (text-xs),
     starile :hover ale linkurilor mici din nav mobil / footer / contact.
   Raman pe #FA3C00 (verificate individual, contrast suficient): btn-accent si
   lang-btn (text alb pe fundal accent solid), cifrele din stats bar, .stamp,
   .text-accent-gradient din H2-uri, initialele din echipa, toate bordurile,
   punctele, barele si iconurile. */
