[frontier] Vision-only GUI agents fail on text-heavy interfaces while DOM agents fail on canvas, maps, and WebGL apps

Build a hybrid perceiver: feed the accessibility tree or DOM for text and structure, feed a screenshot for global layout, and let the model choose which signal to trust. When using screenshots, overlay set-of-marks from detected interactable regions.

Journey Context:
DOM agents miss visual state rendered on canvas, video, or maps; screenshot agents misread text and confuse decorative icons with buttons. A11y-CUA and OmniParser both show that combining structural context with pixel grounding is the only robust path. This is why production computer-use loops now expose both signals.
