/* ============================================================
   Lastslate — animated demo clips
   Real components, scripted like film clips.

   Every component below is lifted VERBATIM from the Electron
   app's renderer stylesheet (screenplay-app/src/renderer/css/
   app.css) and scoped under .lsdemo: titlebar, branch badge +
   dropdown, screenplay page + element classes, status bar, AI
   pane (tabs, bubbles, chat-status, composer, role pill +
   popover), slash menu, new-draft modal, comment sidebar,
   presence avatars, and y-prosemirror remote cursors.

   Deviations from the app, on purpose:
   - traffic-light dots are visible (macOS draws the real ones)
   - the page uses a scaled inch (--in) so a US-Letter page fits
     a marketing clip; all element indents keep their exact
     inch-based proportions
   - the page's top margin is cropped, film-style

   Pairs with demos.js. Clips loop on screen, pause off screen,
   have a pause control, and freeze to a finished still under
   prefers-reduced-motion.
