/* WhatsApp (Web + desktop, 2025-26) — components, built only from whatsapp-tokens.css.
   Study copy for internal design education. WhatsApp's brand and product belong to WhatsApp LLC / Meta.
   Every part has hover, focus, pressed, selected and disabled states. No decorative pseudo-element drawings
   (bubble tails are real inline SVGs), so parts copy cleanly into Figma.
   Sizes come from the measured screens unless the token says [real]. */
