Model Colour + Label System
KForge uses a simple colour-based labelling system to help users quickly understand
the expected cost, risk, and usage profile of a model.
These labels are designed for human decision-making, not billing precision.

Important Notes
- These labels are informational only
- Billing, limits, and availability are determined by the provider
- Users assign labels manually per model
- Labels describe expected usage patterns, not guarantees
KForge does not enforce cost or block usage.
The goal is clarity, not restriction.
