/* B6B — Credi public (GUEST) launcher + chat panel — clients box.
 *
 * Ported from the marketing launcher styles (credicorp.co.uk
 * resources/css/components/credi-launcher.css). Self-contained: every custom
 * property has an inline fallback literal so the launcher renders correctly on the
 * clients guest pages (/apply, /login, /register) whether or not a token sheet is
 * present. Deployed standalone to public/assets/css/credi-launcher.css and loaded
 * by layouts/document.php on the guest surfaces (the launcher partial self-guards
 * on GUEST, the dock on AUTH, so exactly one renders per request).
 *
 * CSP-safe: pure stylesheet, no inline style, no @import of remote origins.
