/* PPM Kit site styles.
   Layout follows the Goodfellow template: utility bar, sticky header with mega menus,
   dark hero with an art card, a dark band, card grids, a CTA band and a dark footer.
   Palette and type are PPM Kit's: teal for actions, ink for text, amber only as the
   "sign here" accent (dark text on it, never amber text on white), amber soft behind
   [PLACEHOLDERS] set in IBM Plex Mono. */
