Dockerfile.prebuilt

# Dockerfile for pre-built application
# Uses pre-compiled .NET publish output (framework-dependent)
# Much faster than building inside Docker - same output works on all architectures
#
# Runtime: chiseled-extra — distroless Ubuntu Noble with ICU globalization data,
# non-root (UID 1654) by default, no shell/package manager.
# The -extra variant is required because the app uses culture-aware localization (en-US).
