  # The suite outgrew the runner the same way the integration suite did: the
  # single job passed at ~18 minutes against a 20-minute cap, and the settings
  # geometry measurements pushed it over. Same remedy, split rather than raise:
  # Playwright shards, each with its own database and production build, and
  # a gate job below that carries the exact name branch protection requires.
  # Two shards grew to 14–19 minutes against the 20-minute cap once the
  # mobile route sweep landed, and a slow runner tipped them over; three
  # shards with a 30-minute cap leave room for both.
