/* --- styles/components/course-orbit.css --- */

/* ============================================================
   course-orbit.css — Reusable animated course hero.
   A central core surrounded by 4 rotating concept nodes plus
   a rotating concept-copy panel. Used on Course Pillar pages
   (Bio, HUG, CSP, …) and optionally on the home page hero.

   Per-course theming via CSS variables on the parent:
     --orbit-accent       (node fill / glow / ring)
     --orbit-accent-dark  (hover / focused state)
     --orbit-accent-light (subtle accents)
   Set on .course-orbit or any ancestor element via inline style.

   Markup pattern:
     <div class="course-orbit-visual">
       <div class="course-orbit" style="--orbit-accent:#16a34a">
         <span class="course-orbit-node">ATP</span>
         <span class="course-orbit-node">DNA</span>
         <span class="course-orbit-node">Cell</span>
         <span class="course-orbit-node">Energy</span>
         <div class="course-orbit-core">
           <div class="course-orbit-core-dot"></div>
         </div>
       </div>
     </div>
     <div class="course-orbit-copy" data-orbit-copy> ...initial copy... </div>
     <script type="application/json" data-orbit-concepts>
       [{"eyebrow":"...","title":"...","desc":"..."}, ...]
     </script>

   The /js/course-orbit.js module reads the JSON, rotates the
   .is-changing class on nodes, and updates the copy panel.
   Respects prefers-reduced-motion (no rotation, first concept).

/* --- styles/components/unit-page.css --- */

/* ============================================================
   unit-page.css — Reusable styles for course unit pages.
   First used by AP Human Geography Unit 1, but designed to be
   shared across Bio, CSP, and other course unit pages.

   Hero theming via CSS variables so each course can re-color:
     --unit-accent     (primary accent — buttons, pills, highlights)
     --unit-accent-bg  (soft accent background tint)
   Set on .unit-hero or any ancestor element.

   Unit-page sections supported:
     .unit-hero           Layered hero with answer pills + dashboard
     .aeo-quick-grid      People-also-ask answer cards
     .aeo-answer-card     Single quick-answer card
     #diagnosticBox       10-question unit diagnostic
     #flashCard           Vocab flashcards
     .section             Generic content section wrapper
