/// <summary>
/// Place on any world object (a button prop, a lever, a sign — anything with a collider).
/// When a player looks at it and presses E, it calls Toggle() on the assigned targets.
///
/// SETUP — three steps:
///   1. Add this component to a GameObject that has a collider (so the raycast hits it).
///   2. Set PromptText to whatever the player should see ("Lower bridge", "Start cable car").
///   3. Drag target components into the relevant slots. Leave unused slots empty.
///
/// You can assign multiple targets — e.g. a button that starts the cable car AND
/// enables a turret at the same time. Just fill in as many slots as you need.
///
/// NETWORKING:
///   The RpcActivate broadcast means any player pressing E fires the action on
///   all clients simultaneously. Target components (BasculeBridge, JointAnchorMover
///   etc.) handle their own physics authority internally.
/// </summary>
