/* ─────────────────────────────────────────────────────────────────
   Block: FAQ — native <details>/<summary> accordion (T9)
   ----------------------------------------------------------------
   Uses native semantics for keyboard + screen-reader a11y. Chevron
   rotates on [open]; smooth max-height transition uses :has() with
   a graceful fallback (open content simply expands without animation
   in unsupported browsers).
   Tokens used: --ds-cta, --ds-accent, --ds-paper, --ds-ink,
                --ds-font-heading, --ds-font-body, --ds-space-*.
