   5. CART / CHECKOUT MODAL SHELL
   Reuses .inquiry-overlay / .inquiry-modal from style.css, but style.css
   only styles the CLOSE BUTTON and MODAL HEADER for #inquiryOverlay
   specifically (by ID) and for .admin-login-box — it does not have a
   generic rule any other overlay can inherit. Without the block below,
   the × has no positioning (floats top-center, no circle background) and
   any .inquiry-modal-header content (like the checkout logo) has no size
   constraint and renders at native size. This block fixes both, scoped
   to #cartOverlay / #checkoutOverlay only — style.css itself is untouched.
