   Deliberately styled and sized to match the site's existing .float-btn
   icons (WhatsApp/Call/Book/Back-to-top) and placed as part of that same
   stack in the HTML, so its position is guaranteed never to overlap
   anything — it inherits the exact same, already-working placement
   logic (including the mobile offset above the sticky bar) instead of
   duplicating fragile positioning math. */
