  mapping_notes: "No direct Lightning Base Component - implement with custom footer and CSS positioning"

accessibility:
  keyboard_support:
    - "Tab to navigate to footer buttons"
    - "Enter or Space to activate buttons"
  screen_reader:
    - "Footer landmark announced if using footer element"
    - "Button labels announced clearly"
    - "Action sequence communicated"
  aria_attributes:
    - "role='contentinfo' if using div instead of footer"
    - "Buttons should have clear aria-label if needed"

usage_guidelines:
  when_to_use:
    - "For long forms that extend beyond viewport height"
    - "When form actions need to remain always visible"
    - "For edit or create flows with Save/Cancel actions"
    - "In modal or page contexts with critical actions"
  when_not_to_use:
    - "For short forms that fit in viewport"
    - "When inline form actions are sufficient"
    - "In contexts where fixed positioning causes issues"
    - "On small screens where footer takes too much space"
  best_practices:
    - "Keep action buttons clearly labeled and visible"
    - "Place primary action on the right (e.g., Save)"
    - "Include Cancel or secondary action on the left"
    - "Ensure footer doesn't obscure important content"
    - "Consider mobile viewport height limitations"
    - "Provide adequate padding around buttons"
  common_mistakes:
    - "Overcrowding footer with too many actions"
    - "Poor color contrast on footer background"
    - "Forgetting to account for footer height in page layout"
    - "Not handling mobile viewport properly"
    - "Missing keyboard navigation support"
