/* EMPN brand overrides for MkDocs Material.
 *
 * Goal: light, airy, low-density. Cream background, navy primary,
 * orange accent for emphasis. Freight Display Pro Book for headings,
 * Söhne for body. Matches the visual identity of empn.eu.
 *
 * Brand tokens mirror plugins/empn-core/shared/empn/visuals/design-tokens.yaml.
 * Update both in the same commit when the brand palette changes.
