/**
 * The Dashboard shell's own stylesheet (ADR 0058): what inline styles cannot express — hover,
 * `:focus-visible`, a reduced-motion override — for the shell's navigation, account menu, tooltip,
 * and drawer.
 *
 * Every value is a design token (ADR 0039), never a literal colour. Every class is `ek-shell-`
 * prefixed, so nothing here can collide with `@ekklesia/ui`'s `ek-` elements, and it is installed
 * into the shell's own document only: each module artifact still mounts in its own isolated root
 * (ADR 0040), which this stylesheet cannot reach.
