/*!
 * WizardML7 Theme Kit — drop-in dark theme + live color switcher + twinkling starfield.
 * Usage: <script src="wizard-theme.js" defer></script>  (place near the end of <body>)
 *
 * Exposes CSS variables you style your page with:
 *   --accent       e.g. #13C4DC   (also --wz-accent)
 *   --accent-hot   brighter hover shade
 *   --accent-rgb   "19,196,220"   -> use rgba(var(--accent-rgb), .3) for glows
 *
 * The chosen theme is saved to localStorage under "wzml7_theme". Because every
 * page on https://wizardml7.github.io/* shares one origin, a visitor's choice
 * automatically follows them across all of your project pages.
 *
 * Options (set BEFORE this script loads):
 *   window.WizardTheme = { stars: true, switcher: true, default: 'teal' };
