/**
 * BLNK Chat widget.
 *
 * Reskinned from the original dark indigo/purple prototype onto BLNK's own palette: cream
 * ground, ink text, one orange accent, and the pill geometry (9999px) the site uses everywhere.
 * Microcopy is JetBrains Mono, uppercase and letterspaced, exactly as the site labels its
 * sections; body copy is Archivo.
 *
 * Everything is namespaced under .blnk-chat and scoped tightly, because this drops onto a page
 * whose own styles are almost entirely inline and would otherwise leak in.

 * is painted UNDERNEATH it while the native one is still suppressed, leaving no pointer at all

 *
 * Restoring it here rather than lowering the panel or raising the theme's cursor keeps the fix
 * self-contained: the plugin has to work on any site, including ones with no custom cursor. It
