Accessibility Commitments

WCAG alignment

• Follows WCAG 2.1 AA success criterion 1.1.1 by providing text alternatives for canvas interactions and exposing keyboard-accessible controls.¹
• Tool buttons include discernible text labels, focus rings, and ARIA attributes.
• All color palettes meet contrast ratios of at least 4.5:1 against the default background.

Keyboard support

• Every toolbar control is reachable via Tab and Shift + Tab.
• Keyboard shortcuts provide redundant operation paths for pointer-only actions (add text, undo, export, navigate pages).

Screen reader cues

• The editor region is wrapped in a landmark with the label “PDF annotation workspace” so users can jump to it quickly.
• Dynamic status messages (e.g., export success) will use aria-live regions in an upcoming release.

Ongoing audits

• Automated checks run via npm run a11y (powered by Pa11y) before deployment.
• Manual testing uses VoiceOver on macOS and NVDA on Windows each major release.
