   Tokens aligned with SM_Aprendizaje_Ilimitado_Plugin (paper #f5f3ef,
   slate ink, brand green #00804C, neutral rules, soft shadows).
   Editorial soul preserved: Fraunces serifs for display + chat, kicker ¶,
   Dramatis personae card, decimal-leading-zero objective numbering.
   Layout: drawer-style objectives panel (chat is full-width; objectives
   live in a floating panel that slides in from the right).
