Use accessibility-tree navigation where possible; reserve screenshots for verification and visual anomaly detection.

## Body
The strongest browser-agent projects are leaning on accessibility trees for deterministic interaction, then using screenshots to verify layout, movement, and visual state. This pattern lowers token cost and reduces selector drift.
