Exact input

Prompt

You are evaluating a user interface screenshot for objective rendering defects.

Check only for these visible issue categories: viewport_cropping, container_clipping, text_overflow, element_overlap, obscured_actionable_control, or broken_responsive_reflow. Do not report subjective design preferences, copywriting concerns, or accessibility assumptions.

If there is one visible issue, return its category and the tight affected region on a normalized 0 to 1000 grid. If none of these issues is visible, return has_issue=false and null category and region values.

Return only data matching the supplied JSON schema. Do not describe your reasoning.
