## 🧭 Reflow Risk (WCAG 1.4.10)

Page-level indicator: resizes to 320 CSS pixels wide and checks for horizontal overflow. This is a risk indicator, not a conformance verdict — see [Behavioral Accessibility Automation](https://github.com/mgifford/ACCESSIBILITY.md/blob/main/examples/BEHAVIORAL_ACCESSIBILITY_AUTOMATION.md) for what it can and cannot detect.
