/* =========================================================================
   v4 «Sistema colibrì» — il marchio usato con coraggio.
   Due colori pieni (viola #513c90, giallo #e7bd0f) + molta aria bianca.
   Inchiostro #1c1c1c sul bianco; il giallo non è mai testo su bianco
   (#7a6200 al suo posto). Angoli 0. Nessun gradiente, nessun velo.
   Device ricorrente: la traccia di volo (SVG .v4-trace) — al caricamento
   nell'hero, allo scroll nel metodo. I cerchi esistono solo come tappe
   sulla traccia (nodi, punti della scala, marcatori del problema).
   Carico sopra style.css: qui si ridefiniscono i token e le classi
   condivise, così le 15 pagine interne prendono la stessa pelle.
