Adds cross-cutting accessibility features: - ARIA roles (graphics-document, graphics-object, graphics-symbol) on SVG structure with auto-generated labels from axis config - Keyboard navigation state machine: arrow keys traverse layers/points, live region announcements with 150ms debounce, focus ring styling - Hidden data table fallback for screen reader access (500-row cap) - Screen-reader-only utility class, focus ring CSS All features skip sparkline mode. Existing functionality preserved. JS: a11y/aria.js, descriptions.js, keyboard-nav.js, data-table.js CSS: focus ring, sr-only, data table styles Tests: 6 JS a11y contract tests Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
