        /* SMOOTH ACCORDION COLLAPSE (shared by Q&A and the registration form's sections).
           Native <details> normally snaps open/closed instantly, and browsers vary in how
           they hide non-summary content internally — so instead of relying on that, we
           explicitly force height:0 (collapsed) vs height:auto ([open], for first paint
           and no-JS baseline) ourselves. JS (see index.js initAccordionAnimations) animates
           this wrapper's height between 0 and its natural scrollHeight on toggle, then
           clears the inline style so these steady-state rules take back over. */
