+# CJIS Co-pilot: Themes Classifier
+
+Part of the Climate Journalism Intelligence System (CJIS) v3.0 "Journalistic Co-pilot".
+
+## Architecture
+- Base: Climate-pretrained DeBERTa (MLM on 20k climate articles)
+- Head: Specialist classifier for themes
+
+## Task
+Themes classification for climate journalism articles.
+
+## Labels (10)
+- `emissions_carbon_pricing`
+- `climate_finance_development`
+- `food_security_public_health`
+- `renewable_energy_tech`
+- `fossil_fuel_industry`
+- `grid_infrastructure`
+- `just_transition`
+- `climate_litigation`
+- `extreme_weather_events`
+- `biodiversity_ecosystems`
+
+## Usage
+```python
+from transformers import pipeline
+
+classifier = pipeline(
+    "text-classification",
+    model="maai-org/cjis-themes-classifier",
+    return_all_scores=True
+)
+
+result = classifier("Your climate article here...")
