   Floating site widgets (every public page)

   Two controls pinned to the bottom-right corner:
   · Back to top — appears once the page is scrolled, with a ring
     that fills as the visitor reads.
   · WhatsApp composer — opens a small chat panel; sending hands
     the typed message to WhatsApp.

   Kept at z-index 90 so the mobile drawer (105) and the toast rail
   (2000) always win.
