/* Think Ahead — component primitive styles.
 * Class styling for the reusable React components in components/*.
 * Mirrors the production marketing-site classes (see ui_kits/website/styles.css)
 * so primitives render identically wherever the design-system bundle is mounted.
 * All values resolve to --ta-* tokens from colors_and_type.css. */
