AnimationController drives playback of one or more SWMMResultsLayers using a primary/secondary model. The primary layer's time grid is authoritative; each secondary layer is snapped to its nearest period via SWMMResultsLayer::periodIndexForDateTime on every tick.

Ownership: the controller is owned by SWMMVis. Whenever a new results layer is added to the canvas it is auto-promoted to primary and the prior primary silently becomes a secondary. The user may re-designate via the layer-tree context menu "Set as Active Results Layer" → SWMMVis::setActiveResultsLayer.

Tick interval = (primaryLayer->reportStepSeconds() * 1000 / speed), clamped to kMinIntervalMs so the UI stays responsive.
