/* MONO360 — shared design language. Single source of truth for every page. */
/* ═════════════════════════════════════════════════════════════════════════
   MONO360 — corporate site
   Register: technical. Sentence case, cold near-black, mono for data,
   real buttons, grid fields instead of engraving.

   STRUCTURAL RULE, borrowed from horizonpmo.io v3:
   the page is white; the key messages arrive in full-bleed black bands.
   Black is used for statements, never for chrome and never for surfaces.

   SIGNAL COLOUR RULE:
   #3355FF appears only where something is governed, live, or over the line —
   the Venn intersection, the overhang past capacity, gates that have fired.
   Never on a heading. Never decorative. Never on a surface.
