(function(){
try {
window.__ctm_cvars = window.__ctm_cvars || [];
function q(name){
try { return new URLSearchParams(location.search).get(name) || ''; } catch(e){ return ''; }
}
function ls(){
try { return localStorage.getItem('ctCartToken') || ''; } catch(e){ return ''; }
}
function sanitize(x){
return (x || '').toString().replace(/[^A-Za-z0-9._~\-]/g,'').slice(0,128);
}
var token =
(typeof window.cometToken === 'function' ? window.cometToken() : '') ||
q('comet_token') ||
ls();
token = sanitize(token);
if (token) window.__ctm_cvars.push({ _comet_token: token });
