/* =====================================================================
   Floating Action Buttons — WhatsApp chat widget (bottom-right) + call
   button (bottom-left). Site-wide: markup lives once in
   includes/footer.php, so every page that includes the shared footer
   gets both. Behavior in assets/js/floating-actions.js.

   z-index sits above the header (100) but below the Apply Now modal /
   gallery lightbox (300, see apply-now.css / gallery.css) — deliberate,
   not an oversight: both of those are full-viewport overlays, so once
   either is open it visually (and for pointer-events purposes) covers
   these buttons automatically. No extra JS needed to "hide" them while
   a modal is open.
