// The hand-assembled world the unit tests and the benchmarks drive: a
// component storage plus the four other pieces a `PipelineContext` borrows.
//
// Building the context directly is what lets a test hand the tick an explicit
// dt, which is what makes timers, delays, and cooldowns deterministic.
