/*
 * Organisation hub chrome (documentation/organisation-hubs/plan.md §9, §12,
 * §13, H22). Loaded by layouts/scripts/hub.phtml AFTER style.css and
 * darkmode.css, so the hub's colours win the source-order ties those sheets
 * rely on. The colours themselves are custom properties the layout declares
 * on body.hub-page (light) and html.theme-dark body.hub-page (dark):
 *   --hub-primary, --hub-primary-rgb, --hub-primary-hover, --hub-on-primary
 * — all validated hex from Hansa_Hub_Color, never raw input.
 *
 * Only accents move to the hub colour: buttons, the hover state of links,
 * focus rings, the current-page marker and the promo accent. Body text and
 * surfaces stay ESL's (§6: "keep body text and surfaces readable").
