       of the configurator panel. The widget's own position (right/bottom 90px,
       from x/y_offset in its Kommo settings) is GLOBAL to every site using the
       widget — the website wants it bottom-right — so we override per-page
       here instead. The panel anchors to the holder's right edge and expands
       left (.amo-livechat_bottom-right), so flip its anchor too or it lands
       off-screen. Verified live against the booted widget on staging. */
