/* css/core.css — design tokens + shell + shared components for Mapa de Tiendas.
 *
 * Direction: quiet, precise "analyst's workbench". Neutral zinc greys carry the UI; the crimson of
 * the slide's legend panel is the only accent (primary actions, active states, focus). Type:
 * Instrument Sans (UI) + Bricolage Grotesque (brand/display); both inlined in vendor/fonts/fonts.css.
 * Module stylesheets (maps.css, maps-ui.css, db.css) reuse these tokens and components — see
 * docs/styleguide.html for a live catalogue.
