/*
 * Block: accordion  —  rebuilt from the prototype FAQ (kitchen-sink .faq/.faqs).
 * Root: section.accordion-area > .accordion > .accordion-section.
 * ------------------------------------------------------------------
 * The generic accordion COMPONENT (css/components/accordion.css) is the
 * "hairline, no box" treatment shared by how-to-apply and course-list
 * accordions. This block gives the pagebuilder accordion the prototype's
 * boxed-FAQ look instead, scoped under .accordion-area so the shared
 * component is untouched for its other consumers.
 *
 * Mechanics preserved: app.js toggles .accordion-section-active on the
 * .accordion-section and aria-expanded on the inner <button>. The panel
 * animates via max-height. The FontAwesome <i> stays in the markup but is
 * hidden; a token plus/cross marker replaces it (real markup has no svg).
