• Value display and formatting
• Responsive behavior during interaction

Accessibility Requirements:

• Proper keyboard navigation support
• Focus indicators that match PV8 style
• Value announcements for assistive technology

Acceptance Criteria:

• All navigation elements function smoothly with PV8 styling
• Drag interactions feel responsive and natural
• Keyboard navigation works correctly
• Components integrate well with surrounding content
• Test page demonstrates all interaction patterns

Deliverables:

• CSS for slider/scroller/progress styling
• JavaScript for drag interactions and keyboard support
• Test page with interactive examples
• Accessibility testing results and documentation

Dependencies:

• Can be developed in parallel with Style Core Views: Application View, Headers, Folder Tabs, Menu Bar, Floating Bar #11-13 after Custom Components: Build PV8-specific UI components not in base 98.css #10 is complete
