/**
 * VoizPanda chat widget — all rules scoped under #voizpanda-chat-root only
 * (no :root / html / body) so themes and Elementor are unaffected.
 *
 * === DO NOT REGRESS (historical breakages) ===
 * - NEVER add  pointer-events: none   on #voizpanda-chat-root (broke FAB clicks)
 * - NEVER add  contain: paint          on #voizpanda-chat-root (hid SVG icon)
 * - NEVER add  isolation: isolate      on #voizpanda-chat-root (broke stacking in some themes)
 * If the FAB stops clicking, check for overlapping third-party widgets (WhatsApp, cookie banners)
 * and adjust --voizpanda-offset-bottom / --voizpanda-offset-right in WP admin or below.
