/* Microcosm — design tokens for microcosm.institute.
 * Native tokens vendored from constellation-design/tokens/microcosm.css
 * (constructed 2026-08-02). The economy in miniature. Verdigris: the patina
 * that grows on bronze. Light-native; opt-in dark via [data-theme="dark"].
 *
 * The compat block below defines every @policyengine/ui-kit semantic token
 * this site's pages still reference (the site wore the PE design system from
 * PR #5 until 2026-08-07), valued from the Microcosm palette so those
 * references resolve in-identity. Pages migrate off the compat names over
 * time; new styling should use the native tokens.
 *
 * NOTE: style.css re-purposes --paper as its primary-TEXT alias (a holdover
 * from the site's dark-native first cut), which shadows the native surface
 * token below on every page that loads both files. Compat values that need
 * the paper surface therefore use the literal #FCFEFC, never var(--paper).
