/* ============================================================================
   Brand guidelines (Pages/Brand.cshtml). Ported from "Brand Guidelines.dc.html".
   Hero backdrop is "Hero Backdrop" with pattern "Radial fan", tone Blue, no bottom glow.
   Shared pieces (.hero, .section, .eyebrow, .btn, .tools-cta__panel, ...) live in site.css. Razor only, no JS:
   the design's scroll-reveal animation and Font Awesome are not ported. Every colour swatch is a class here,
   and the swatch values are the tokens in tokens.css (the page documents the same palette the site uses).
