Implement WCAG 2.1 compliant keyboard navigation for full accessibility. Core requirements: (1) All interactive elements accessible via keyboard (Tab, Shift+Tab, Enter, Space, Arrow keys), (2) No keyboard traps (users can navigate away from any element), (3) Visible focus indicators (3:1 contrast ratio minimum against background). Key patterns: Tab/Shift+Tab navigate between focusable elements (buttons, links, inputs), Enter activates buttons and links, Space toggles checkboxes and activates buttons, Arrow keys navigate within dropdowns, radio buttons, sliders, Escape closes modals and menus. HTML semantics: use native elements for free keyboard support:
