   Brand tokens (--primary-color / --secondary-color / --accent-color) are the
   3 admin-editable channels: their base values below are fallback defaults,
   but AdminCP > Theme Manager overrides them at runtime via an inline
   :root block injected in <head> (see includes/theme_helper.php::getThemeCSS()).
   Everything else in this file should reference the semantic token names
   below rather than hardcoded hex, so a future theme change stays global. */
