/* =========================================================================
   MyTutor — TOEIC テスト対策コース — hub page
   Built to the REVISED "Clear Professional" guideline. Scoped under .th.
   Same shared template as the TOEIC Speaking / Writing pages.
   - Plain .course-eyebrow (no leading line).
   - Shared mt-course-layout-page / mt-course-layout-wrap width utilities.
   - Free-trial CTA via get_footer() → includes/free-trial-cta.php (services.css).
   - .mt-card hover only on clickable a.mt-card; div.mt-card never lifts.
   Shared classes mirrored here so the page renders standalone; remove if
   css/main.css defines them globally.
