Declared side by side, so they read as parallel; the lab runs a single
act_runner with one slot, so the backend job starts at the exact second the
frontend one ends. Measured across runs #86-#91: ~4 + ~6 = ~10 minutes from the
push, not ~6.
Written down because believing the comment cost something real — the ops
release read-back budgeted the max instead of the sum and timed out on its
first live run, reporting a still-running gate as a failing one.
