"""Unified Credit System — tool cost registry and credit constants.
|
||||
|
||||
Every tool has a credit cost. Lighter tools cost 1 credit, heavier
|
||||
server-side conversions cost 2, CPU/ML-intensive tools cost 3,
|
||||
and AI-powered tools cost 5+.
|
||||
|
||||
This module is the single source of truth for all credit-related
|
||||
constants consumed by policy_service, credit_service, and the
|
||||
frontend config endpoint.
