• Verify that a "Darwin Core" section appears below the field description and is clearly labeled
• Confirm the section can collapse and uncollapse
• Click on the section header and verify it expands, then click again and verify it collapses without layout issues
• Select a field that has mapped Darwin Core terms and expand the section
• Verify each mapped term displays:
• Term name
• Full IRI
• Description
• Vocabulary
• If multiple terms are mapped to the same field, verify each appears as a separate list item
• Select a field with no mapped Darwin Core terms, expand the section, and verify the message:
  "No Darwin Core terms mapped to this field."
• Verify the section is read-only (no inputs, dropdowns, or editable controls)
