/* =====================================================
   Course: 体験 (Trial) — bespoke page skin
   Loaded only on single-course-trial.php.
   All rules are scoped under .tr and use tr- prefixed
   classnames so nothing here can collide with main.css.

   Reuses the site's existing Terracotta / Greige / Ivory
   tokens (see main.css :root) — no new hues are introduced.
   Unlike the training-pilates / bridal pages (which split
   into two registers), this course only needs one accent:
   its whole story is "removing the anxiety of a first
   visit," told through a single flip-card interaction
   rather than a color split.
