/* SideSeat site kit.
 * Colours come from the desktop app's themes (light = theme B, dark = theme A) and the logo; see brand.md.
 * Flat colour only: no gradients, no drop shadows, no backplate behind the logo. The recurring shape is the
 * logo's diamond facet, used as the marker on badges, notices, steps and selected options.
 * Class names: block, block__part, block--variant. Kit reference with markup: web/dev/UI-KIT.md. */
