/* ============================================================
   whatsapp.css — WhatsApp entry points. MOBILE FIRST.
   Adapted from the StandScale site (qr.css) to the Kybernete
   palette and Bootstrap layout.

   The same wa.me link appears in up to five places:

     .nav-wa    — navbar, outside the hamburger so phones see it
     .qr-hero   — inner-page hero, standing code on the right
     .wa-band   — a full-width band part-way down the page
     .qr-card   — inside the Contact section
     .wa-dock   — fixed bottom-right, visible at all times

   Every QR is wrapped in the link it encodes, so a desktop
   visitor scans it and a phone visitor just taps it.

   The floating dock deliberately uses real WhatsApp green —
   that bubble is a recognised affordance.
