/* whatsapp-kit.css (v2, 2026-10-21): 3D social coins (Facebook, WhatsApp, Instagram, X, LinkedIn, YouTube), the floating WhatsApp coin and its chat panel.
   One folder, no external requests. Markup: snippet.html. Behaviour: whatsapp-kit.js. Guide: README.md.

   Z-INDEX SCALE (documented; change a number only here or on :root)
     0-49   page content, headers, page menus
     50     --wa-z-fab    floating coin (above page content; page overlays at 55 and up cover it and the script hides it anyway)
     80     --wa-z-scrim  dim layer behind the chat panel
     81     --wa-z-panel  chat panel (top of the kit)
   Pages keep loaders and cookie bars above 90.

   TOKENS (all on :root; a page overrides any of them in its own CSS, never by editing this file)
     --wa-size, --wa-gap   floating coin size and its distance from the screen edges (phones: 58 px, 16 px)
     --wa-clear            room a page keeps under its last footer line: size + gap (same name as the old wa-float)
     --wa-lift             how far the coin rises while a link, button or field sits under its corner: size + 16 px (phones: bottom 16 px to 90 px)
     --wa-coin             social coin size (48 px)
     --wa-ink, --wa-muted, --wa-line, --wa-paper, --wa-wash     text, quiet text, borders, panel ground, greeting ground
     --wa-btn-bg, --wa-btn-fg, --wa-btn-hover                   the "Send on WhatsApp" button
     --wa-ring, --wa-ring-gap    focus ring and the gap ring under it (visible on light and dark grounds)
     --wa-radius           the one corner radius (panel 16 px; inner boxes use this minus 4 px)
     --wa-font             type stack (the page's own font-face is used when it loads one) */
