/**
 * Public mascot chat widget — standalone, loaded only on the login page and
 * fafm_public_page docs pages (see includes/class-fafm-visitor-chat.php).
 * Deliberately does NOT depend on assets/css/core.css's --fafm-primary*
 * tokens or assets/css/modules/ai-assistant.css's .fafm-ai-chat/.fafm-ai-mascot
 * rules — neither stylesheet loads on these pages, so this defines its own
 * small, self-contained token set instead of importing the admin bundle.
