# Deploy versioned simulation app to Modal

# Required env vars: POLICYENGINE_VERSION, POLICYENGINE_US_VERSION, POLICYENGINE_UK_VERSION
#
# Deploys a versioned app named policyengine-us{X}-uk{Y} and updates
# the Modal Dict version registries so Cloud Run can route to it.
# No separate gateway app — Cloud Run handles routing directly.
