/* ==========================================================================
   GERMAN-A2-COURSE.CSS — scoped styles for german-a2-course.html,
   the A2 Elementary Course landing page linked from german-courses-page.html.
   Mirrors german-a1-course.html/.css (the A1 version): an A2 Course
   context card + preview grids of the site's planned A2 flagship pieces.
   None of those pieces (story/word reference/grammar path/vocabulary
   courses/writing practice) have real pages yet, so their cards here are
   plain (unlinked) previews rather than <a> pieces — no .cj-course-stats-row/
   .cj-time-commitment/.cj-course-links either, since there's nothing real
   yet to put a number on. .card/.hub-tag-badge/.topic-chip-a2-* are
   inherited from see-test.css.

   This file also re-themes the whole page: it redeclares the shared design
   tokens (--bg/--surface/--ink/--accent/--gold/--line/--serif/--color-*)
   with the same "modern Bauhaus" values used on german-a1-course.css/
   german-courses-page.css. Because this stylesheet is only ever linked
   from german-a2-course.html and loads after see-test.css, every
   shared component that reads those tokens picks up the new palette on
   THIS page only. Uses "html:root" rather than plain ":root" for the
   override — see a1-highlights.css for why that extra specificity is
   worth the insurance.
