/* ─────────────────────────────────────────────────────────────────
   IELTS Speaking — lesson page touches.

   The index page reuses Reading's flat .rd-lessons-grid styles
   directly; this file only carries Speaking-specific lesson-page
   accents and two custom block types (sp-compare, sp-drill-cta)
   plus the practice-page "coming soon" stub.

   Lesson page — group-tinted accent + Speaking-only blocks.
   Reuses .rd-lesson-* styles from the Reading lesson page;
   what we add here is the group-tint and two new blocks.
