Analyze this document image and extract ALL content with precise layout structure.

ROW GROUPING RULES (CRITICAL):
1. Elements on the SAME HORIZONTAL LINE must be in the SAME row
2. Multi-line text that forms ONE VISUAL BLOCK should be ONE element with \n between lines
   Example: "COC 92429925\n30 September 2023" is ONE element if vertically stacked together
3. Only create separate rows when there is CLEAR VERTICAL SEPARATION between content
4. Header area (logo + organization name) = usually 1-2 rows
5. Footer area (page number + verification info) = usually 1-2 rows

CONTENT EXTRACTION:
1. Extract EVERY piece of text including reference numbers, dates, fine print
2. For TABLES/FORMS (label: value pairs): label in "left", ":" in "center", value in "right"
3. Merge continuous paragraph text into single elements

For each element provide:
- "content": Exact text (use \n for line breaks within same visual block)
- "type": header, title, subtitle, paragraph, list_item, label, value, footer, logo_area, photo_area, signature_area, qr_code
- "region": "full_width", "left", "right", or "center"
- "style": {"alignment", "bold", "size": "small/normal/large/xlarge"}

TABLE/FORM FLAGS:
- "table_start": true - when a new table section begins
- "has_border_top": true - row has visible horizontal line above (part of table)
- "has_grid": true - table has visible grid lines
- "has_background": true - row has background color

PLACEHOLDERS (keep as separate elements):
- "[Logo Affixed]" for logos/emblems
- "[Photo Affixed]" for photographs
- "[Signature Affixed]" for signatures
- "[QR Code Affixed]" for QR codes

      ]
    }
  ]
}

REMEMBER:
- Same horizontal line = SAME row
- Vertically stacked text in one visual block = ONE element with \n
- Only separate rows for CLEAR vertical gaps
