/*
 * KAI docs theme, layered on docsify's vue.css. Shared by the internal and
 * public sites (assemble.mjs copies it, and docs/theme/, to both).
 *
 * Colours mirror the KAI platform UI design system: ink and soft grey
 * surfaces, brand blue for links and emphasis, a navy palette in dark mode.
 * Everything is a variable below, so dark mode only redefines the palette.
