/* ==========================================================================
   Kromdraai Blomme — the floating WhatsApp button.

   A round forest button with a gold hairline, the WhatsApp mark in ivory and
   a slow breathing ring. The label slides out on a pointer, and the button
   keeps clear of the cookie notice and the footer.

   The legacy stylesheet drew a 16px glyph on top of a green image. This
   replaces it, and it is loaded after that stylesheet so it wins.
