# === Runtime stage ===
# NOTE: Using the SDK image (not runtime-only) because MSBuildWorkspace requires
# MSBuild at runtime for Roslyn compilation (index.ensure_baseline). The SDK image
# is larger (~800MB) but is the simplest approach.
#
# Alternatives:
# (b) Copy MSBuild from build stage into the runtime image — more complex, smaller.
# (c) Use runtime image + pre-built baselines from shared cache only (no indexing).
