+- If the document is too large to generate completely in one response, set "continue": true
+- When "continue": true, include a "continuation_context" field with:
+  - "last_section_id": "id of the last completed section"
+  - "last_element_index": "index of the last completed element in that section"
+  - "remaining_requirements": "brief description of what still needs to be generated"
+- The AI will be called again with this context to continue generation
+- Only set "continue": false when the document is completely generated
+
 The AI should NOT create format-specific structures like "sheets" or "columns" - only use the canonical format with "sections" and "elements".
 
 Write the instructions as plain text, not JSON. Start with "Generate JSON content that..." and provide clear, actionable instructions for creating structured JSON data in the canonical format.
