/**
 * @file
 * FAQ Section — Wealthsimple-style two-column sticky-sidebar accordion.
 *
 * Brand tokens: navy #1C3557, green #3CB944, accent green 2 #1D9E75,
 * heading #0A0A0A, body #45464F, light wash #E8F5E9. Font: Manrope.
 *
 * SPACING — strict 4px rule via the shared rem scale; vertical rhythm halved
 * from the prior build for a tighter, denser column.
 * TYPOGRAPHY — line-height & tracking are inversely proportional to font size
 * (large headings: tight line-height + negative tracking; body: loose + 0).
 *
 * Animation: the open/close height transition is pure CSS (0.3s) using the
 * grid-template-rows 0fr -> 1fr trick on .faq-content-wrapper.is-open
 * (no JS height math). JS only toggles ARIA state + the .is-open class.
