Weighted traffic mix

# Weighted traffic mix — Artillery's `scenario-weights` (Locust @task weights /
# Gatling randomSwitch).
#
# A single scenario whose flow picks one weighted branch per iteration: 70% just
# browse, 20% search, 10% complete a checkout. Each branch is tagged (`branch`)
# so per-path metrics fall out automatically. Tune the weights to model real
# traffic shape without spinning up separate scenarios.
