 * This file is the theme header plus the rules that must exist outside
 * theme.json: layout scaffolding, the header, cards, hubs and the discovery
 * hero. Presentation that an editor should be able to change lives in
 * theme.json; colour roles live in assets/css/color-scheme.css; every block
 * (plugin-rendered and theme-rendered) is styled in assets/css/blocks.css.
 *
 * Colour tokens:  assets/css/tokens.css        (raw brand scales)
 * Light/dark:     assets/css/color-scheme.css  (semantic roles, both schemes)
 * Blocks:         assets/css/blocks.css        (frontend + editor)
 * Editor parity:  assets/css/editor-style.css
