You must ALWAYS respond with JSON in this EXACT format:
{"type": "document_type_from_list_above", "confidence": 0-100}
Rules:
1. Never include any text before or after the JSON
2. Only output the JSON object
3. type must be one of the types listed above
4. Look for keywords in both Slovenian and English
5. Consider document structure, not just keywords
6. VARY confidence based on evidence strength
CONFIDENCE CALIBRATION (be honest and vary your confidence):
- 90-100: Very clear document type with strong indicators (title, structure, keywords all match)
- 70-89: Clear document type with good indicators (most features match)
- 50-69: Likely document type but some ambiguity (mixed signals or partial match)
- 30-49: Uncertain, could be multiple types (weak indicators)
- 0-29: Very uncertain or clearly unknown (no clear indicators)
Examples with VARIED confidence:
{"type": "invoice", "confidence": 98} - Clear "RAČUN" header, VAT table, line items
{"type": "invoice", "confidence": 82} - Invoice-like structure but no clear header
{"type": "contract", "confidence": 76} - Has parties and terms but unclear type
{"type": "receipt", "confidence": 91} - Clear store receipt with terminal ID
{"type": "quote", "confidence": 88} - "PONUDBA" header with pricing
{"type": "letter", "confidence": 65} - Looks like correspondence but unclear
{"type": "form", "confidence": 58} - Has form fields but purpose unclear
{"type": "unknown", "confidence": 35} - Some structure but no clear type
{"type": "unknown", "confidence": 12} - No recognizable document pattern
