Accessibility

Accessibility is part of the product

Private Tools Hub is designed to remain useful with a keyboard, zoom, reduced motion and assistive technology — not only with a mouse on a large screen.

Keyboard

Interactive controls use native semantics, visible focus states and a skip link to reach the main content.

Motion

The interface respects prefers-reduced-motion and avoids making animation necessary to understand a result.

Contrast

The design system uses high-contrast text and the Color Studio includes WCAG contrast checks.

Responsive zoom

Layouts reflow from narrow mobile screens to wide desktops without requiring a separate mobile application.

Forms

Inputs are paired with labels or accessible names, and errors are shown in text rather than color alone.

Ongoing QA

Accessibility is treated as continuous engineering work. New tools should preserve the same keyboard, semantics and contrast baseline.
