/* ============================================================================
   TTA course player + course details (pack v3, 2026-10-02)
   Used by resources/views/Web/courses/playlist.blade.php and course-details.blade.php.
   Tokens = the dashboard-v3 --d-* set (public/css/dashboard-v3.css / dashboard-embed.css §1), re-declared here as
   --cp-* under .tta-cp so the page looks the same standalone (light, or dark when the workspace shell set
   html[data-theme="dark"]) and inside the dashboard Page Zone frame (html[data-theme] from ?theme=, updated live by
   dashboard-embed.js applyTheme). Every selector is .tta-cp-scoped with two classes, which beats the embed skin's
   element rules (body.tta-embed h1 = 0,1,2) without !important. No vh-based heights (the zone frame is sized to
   the page, so 100vh would grow with it).
