Generic accordion fallback (data-faq-item / data-faq-toggle / data-faq-panel / data-faq-icon): handles any accordion using this pattern that has no page-specific script of its own (e.g. Careers). Guarded with data-faq-bound so it never double-attaches on pages (like Home) that already have their own accordion script -- whichever script runs first claims the element via this marker, the other skips it.
