accessibility

Audit and improve web accessibility following WCAG 2.2 guidelines and best practices. Comprehensive accessibility guidelines based on WCAG 2.2 and Lighthouse accessibility audits. Goal: make content usable by everyone, including people with disabilities. Images require alt text: Icon buttons need accessible names: Visually hidden class: Don't rely on color alone: All functionality must be keyboard accessible: No keyboard traps. Users must be able to Tab into and out of every component. Use the modal focus trap pattern for dialogs—the native element handles this automatically. When an element receives keyboard focus, it must not be entirely hidden by other author-created content such as sticky headers, footers, or overlapping panels. At Level AAA (2.4.12), no part of the focused element may be hidden.
