Access is a
release gate.

Structure

• Semantic landmarks, logical heading order, and a skip link.
• Keyboard-operable navigation and interactions with visible focus states.
• Touch targets of at least 44 CSS pixels, with any exception documented.

Perception

• Sufficient contrast, with no information communicated by color alone.
• Reduced-motion support: every nontrivial effect has a calm, static state.
• Static alternatives for interactive diagrams, labeled for assistive technology.
• No flashing above three flashes per second.

Release evidence

The production release includes an audit record for keyboard-only use, zoom and reflow, text spacing, forced colors, and screen readers on desktop and mobile.
