accessibility:
  keyboard_support:
    - "Illustrations are typically non-interactive"
  screen_reader:
    - "Provide descriptive alt text or aria-label"
    - "Use aria-hidden='true' for decorative illustrations"
    - "Ensure accompanying text is accessible"
  aria_attributes:
    - "role='img' on SVG or wrapper"
    - "aria-label with description for meaningful illustrations"
    - "aria-hidden='true' for purely decorative images"

usage_guidelines:
  when_to_use:
    - "For empty states (no data, no results, no items)"
    - "For error or success confirmation screens"
    - "To communicate system status visually"
    - "For onboarding or informational screens"
  when_not_to_use:
    - "As primary content (use as supporting visual)"
    - "For critical information without text backup"
    - "In place of icons for actions"
    - "When space is extremely limited"
  best_practices:
    - "Always pair illustration with descriptive text"
    - "Use appropriate size variant for context"
    - "Provide clear messaging about user action or state"
    - "Ensure illustrations support but don't replace text"
    - "Use consistent illustration style across application"
    - "Consider color contrast and visibility"
  common_mistakes:
    - "Missing descriptive text or heading"
    - "Illustrations too large for context"
    - "Poor color contrast making illustration hard to see"
    - "Relying solely on illustration without text"
    - "Using wrong size variant for space available"
