/**
 * Nibiru Design System — v4.0.0 "Cosmos"
 *
 * Canonical source of truth for the brand. Imported globally by the site
 * (see astro.config.mjs `customCss`) and published verbatim at
 *   https://nibiru-framework.com/design-system/tokens.css
 *
 * v4 is dark-first: the page lives in space, headlines glow magenta-amber,
 * the lotus mark is the star at the centre. Light "paper" surfaces are
 * available via .alt sections for content-heavy reading.
 *
 * All tokens namespaced --nibiru-* so they coexist with other systems.
