#   ./scripts/sync-to-flights-front.sh [target-dir]
#
# Default target: /Users/gnezim/_projects/tims/flights-front/Aeroflot.Flights.Front
#
# The deploy repo has the shape:
#   flights-front/
#     Aeroflot.Flights.Front/   ← app source (target of this sync)
#     deployment/               ← k8s manifests, ci scripts, etc.
# Anything under this repo's top-level deployment/ is copied to the
# sibling deployment/ in the deploy repo so cluster config lives with
# the source that consumes its env vars.
