/* After AI Work v2. Theme: "draft to done", green.
   Every visual device comes from the mark: a dashed grey state (the AI draft), an arrow (the handoff),
   a solid green state (finished work). Brand #119E4B; every neutral is tinted from that hue.
   Inter only. Body 400, UI 500/600, h3/h4 700, large display type 600. Nothing above 700. No gradients. */
