 * to every real build. See TEMPLATE.md for the character spec and the
 * brand-parameter contract (which properties to fill, how tints/shades derive).
 *
 * Character: rounded, warm, airy — humanist type, generous radii, soft two-layer
 * shadows, gentle ease-out motion. Fonts load via <link> in the HTML head.

 * on --color-primary; --color-primary used as link text must hold >= 4.5:1 on
