   Fixed brand identity (mirrors the real company's own brand-locked site) —
   every color below is painted explicitly rather than left to inherit, so
   the page holds its identity on any host background regardless of the
   viewer's OS theme. Palette is drawn from the trade itself: blueprint navy,
   brass-fitting gold, poured-concrete white, site-pencil charcoal. */
