/**
 * EASPNET Live Chat Bridge
 *
 * Custom UI layered on top of the cami (11.cmsrv.cc) chat widget:
 *   1. A "聯絡我們" launcher button (replaces the default polar-bear icon).
 *   2. A "contact panel" popover with several contact options.
 *
 * The cami polar bear (#cami_patrol_tool) is hidden *visually* but kept in the
 * DOM and clickable, because we programmatically .click() it to open the chat.
 * See assets/js/live-chat-bridge.js.
 *
 * Every rule for our own UI is prefixed with the wrapper id (#easpnet-live-chat)
 * so an id-level specificity keeps the theme (hello-elementor) from overriding
 * our styles. The cami bear rule below is the only exception — that element is
 * outside our wrapper.
 */

/* ── Hide the cami polar-bear launcher ─────────────────────────────────
 * Must stay rendered & hittable (not display:none) so JS .click() works.
 * We pull it off-screen and make it non-interactive to the user.
 * (Not inside #easpnet-live-chat — it's the cami widget's own element.)
