WCAG

Web Content Accessibility Guidelines

The accessibility standard most regulations point at. Levels A, AA, and AAA describe increasing strictness; AA is the usual target.

EXAMPLE

AA requires body text to reach a 4.5:1 contrast ratio against its background, and large text or meaningful icons to reach 3:1.

WHY IT MATTERS

It converts "make it accessible" into specific, checkable thresholds. Most failures are design decisions made early, contrast, focus states, target size, and they're cheap then and expensive to retrofit.
