A Scenario is an abstract C# class compiled with the game: Generate picks the galaxy through GalaxyStage (Main or
Prelude, at the scenario's seed, the background noise drawn from the same seed), Stage places the run's first
entities through ScenarioStage (Fit, Bare, Generated, Preset, Player, Place, Cargo), which collects named failures
and admits nothing. RunStart generates the galaxy, the arena under Ambient and admits everything through Zone.Admit,
all or nothing. The aetheria.scenario record, ScenarioShip, ScenarioEntity, RunStart.Check and the null-scenario
branch are cut.
New Game opens a submenu: Tutorial Galaxy and Main Galaxy, then (editor and development builds) Djinni Shakedown,
Starved Reactor, Arcs, Duel, Launcher Angles and Long Haul, each with its brief. MainMenu.Launch is the one way into a
new run; ActionGameManager.PendingScenario carries the scenario to StartGame once.

RunStart (ServerShared, no Unity type) owns what a new run starts with
(docs/scenarios-cut.md, 2.2):
- GenerateArena: the galaxy's entrance pack, generated under the scenario's
Ambient rule. ZoneGenerator.GenerateZone gains `ambient`; false keeps
planets, orbits and stations and generates no ship, turret or wanderer.
- Check: every failure staging a scenario would hit, found with no zone,
touching no store.
- Stage: all-or-nothing. With no scenario, the generated starting-hull ship
at the origin, as StartGame built it. With one, the player preset and the
entities at their authored place and heading with cargo, stance set both
ways through SetIff, a Minion for each piloted one; all through Zone.Admit.
Scenario (aetheria.scenario v1) joins AetheriaStores.CatalogTypes.
RunStartTests stage into a real prelude arena from the shipped catalog and
authored settings.
