/* ---------- Programme colour ----------
 * Every page has a programme colour. Programme pages pick one with a page template
 * (Page > Template in the editor); everything else uses NVT teal. Bright = icons, bars,
 * banners. Ink = text and buttons (passes 4.5:1 on white).
 * Sub-brands use the nearest logo colours (decided 2026-11-11) so the site stays uniform;
 * NVT's own sub-brand artwork may adjust them later. */
