/* =========================================================
   AEM Protocol, DEMO — COMMENTED STYLESHEET
   ---------------------------------------------------------
   Main goals of this stylesheet:
   1. Give the prototype a coherent dark UI
   2. Organize the editor / verifier layout
   3. Support the subtle watermark + hover reveal concept
   4. Keep the styling readable for future reviewers

   This is still prototype CSS, not a production design system.
