/* Alyte shared component layer — the reusable UI primitives extracted from the
 * interactive mock (UI-0-1). Driven ENTIRELY by the tokens in alyte-tokens.css; this
 * file declares NO raw colours of its own, so a brand tweak stays a one-file edit and
 * pages stop re-declaring buttons/cards/tables/pills per <style> block (the drift the
 * token file already fixed for colours — this does the same for components).
 *
 * Load order on a page: alyte-tokens.css, alyte-components.css, then alyte-ui.js,
 * alyte-nav.js. Everything here is plain CSS classes; no build step. See
 * docs/design/UI_BACKLOG.md (UI-0-1) and UI_IMPLEMENTATION_PLAN.md. */
