/**
 * Floating WhatsApp + back-to-top buttons. Loaded on every page (see
 * SPB_Site_Chrome), so this file stays deliberately small and scopes
 * everything under .spb-fab — it must never reach into a theme's own markup.
 *
 * Three independent visibility states stack as separate classes rather than
 * one "visible" flag, because they come and go independently:
 *   is-blocked   — a hero or the footer is on screen, buttons must not show
 *   is-scrolling — the page is moving; they step aside until it settles
 *   is-idle      — settled and untouched for a while; they ease back but stay
