/* Official IHS brand theme (IH Colour Palette, 2026 assets): Forest Green #3B4B40 (Pantone
   4202 C), Charcoal #1A1A1A (Black 6 C), Marble Cream #D6CBB7 (482 C), White — plus derived
   cream/grey tints. --tm is a deepened Forest Green for hover/link accents (the palette has no
   secondary hue). Poppins is the bundled stand-in for the brand's licensed Galano Grotesque.
   Red is reserved for required marks and errors, exactly like the official registration form. */
