/*
 * Courses: public pages ([cbtt_courses], [cbtt_course_withdrawal]).
 *
 * Scope: every rule hangs off .cbtt-courses. The palette variables are set
 * on .cbtt-scope.cbtt-courses by cbtt_courses_inline_css() (specificity
 * 0,2,0, above the suite palette on .cbtt-scope); never on :root. With the
 * palette "theme" they are `inherit`, so on CBTT-Turbo they resolve to the
 * theme's own values and elsewhere fall through to the fallbacks below
 * (one fallback chain per token, defined once on .cbtt-courses).
 *
 * Course colour (--cbtt-course-color, per course from the inline CSS) is
 * decoration on public pages: the teacher's corporate design, an exception
 * to the suite's "status colours only" rule that governs the admin UI.
 *
 * Cacheable views load this file only; uncached views add cbtt-ui.css,
 * which this file does not depend on.
 *
 * Background and text always come from the same source: where a surface
 * colour of the palette paints a box, its text uses the palette's text
 * colour (var(--cbtt-text)); with the theme palette both fall back to the
 * theme (surfaces transparent, text inherited), so a dark theme never puts
 * light text on a white card. Muted text is the current text colour at 72 %,
 * never the suite's light grey token — it stays readable on every surface.
