Annotate agent-produced screenshots/diagrams (draw/point/comment) and send back agent-legibly. Key insight recorded: agents read images natively — drawn-annotations burned into a composite image may be the CriticMarkup-equivalent (human-drawable, agent-legible, no new format). Deliberately demand-triggered → this issue is the trigger's landing place. Design conversation before any build.
