/* ============================================================
   blucode — un marchio di Blu-way S.r.l.
   La grafica nasce dal logo: il quadrato // nel blu di Bluway
   (#0E0D69), il prefisso "blu" in azzurro (#4765AD), la scritta
   geometrica, pesante e senza spazi. Niente nero: il testo e' blu
   scuro. Superfici piatte, angoli vivi come il quadrato, le due
   parallele inclinate (~15°) come motivo.
   Font di famiglia: Montserrat per titoli e testi, JetBrains Mono
   per i dettagli "code" e il payoff.
