/* Daily Build lesson player. See DESIGN.md and docs/lesson-design.md.
   Layout and editor chrome only. Tokens live in tokens.css and shared components
   (.btn .option .feedback .progress .stat .mascot .field) in components.css.
   The page runs in the space theme (<html data-theme="space">).

   The first question comes alone (data-stage="solo"). After it the task docks and the tool slides in
   (data-stage="dock"). Two layouts, one markup:
     >= 900px   task column on the LEFT, AI chat in the middle, your app on the right
                (below ~1060px the chat and the app share one pane and the app becomes a tab)
     < 900px    the tool fills the screen with tabs (Chat, Your app, ...); the task is a bottom drawer
                with two states, open and closed */
