     The branded chip (#25D366, hover #1FBF59) is recorded here as a VALUE, not
     a token, because no ground on this site lets it carry text — white on it is
     2.0:1 / 2.4:1, a WCAG AA failure on the one button that produces the
     enquiry. Recognition is carried by hue, glyph and shape instead:
     - `--color-whatsapp-fill` / `--color-whatsapp-fill-hover`: the fills that
       carry text. White on them measures 5.2:1 / 7.4:1, AA at body size. The
       audience reads these on a phone, on site, in daylight.
     - `--color-whatsapp-text`: link, glyph or outline on a light ground (5.2:1).
     If the client ever requires the literal chip colour, it needs dark text on
     it (`--color-text` on #25D366 is 7.9:1) and it will break WhatsApp's own
     white-on-green convention. */
