/*
 * Éclore Aesthetics — FAQ accordion (VISUAL-DESIGN §5.8)
 * ─────────────────────────────────────────────────────────────────────────────
 * Button-based disclosure held to the narrow measure. Each item is an Inter 500
 * question row with a Terracotta "+" that rotates to "×"; hairline dividers
 * separate items. The panel height animates via grid-template-rows 0fr→1fr +
 * opacity (CLS-safe, no max-height guesswork) — the one sanctioned non-
 * transform/opacity move (§6). The JS removes the no-JS `hidden` fallback so the
 * grid can animate; reduced motion collapses the timing to instant globally.
