/* ==========================================================================
   WhatsApp Floating Button
   Design notes:
   - WhatsApp green (#25D366) is the official brand color, with darker
     #128C7E for depth on hover — kept intentionally separate from the
     site palette to be instantly recognisable as a WhatsApp affordance.
   - z-index 95: above mobile-cta-bar (90) but below sticky header (100).
   - Desktop: bottom-right 32px. Mobile: lifts 80px above mobile-cta-bar.
   - Pulse animation fires once on entry (3 s delay), never loops
     (avoids attention fatigue). Respects prefers-reduced-motion.
   - Tooltip slides in from the right, disappears on touch (pointer: coarse).
