============================================================================ ADVANCED SLOT WIDGETS

AnimatedSlot - Automatically animates between value changes.

Wraps value changes with an implicit animation, providing smooth transitions when the signal emits new values.

Example:

class MyController extends NeuronController {
  late final counter = Signal<int>(0).bind(this);
}

// Basic usage:
AnimatedSlot<int>(
  connect: controller.counter,
  duration: Duration(milliseconds: 300),
  curve: Curves.easeInOut,
  to: (ctx, val) => Text('$val'),
)

// With effects:
AnimatedSlot<int>(
  connect: controller.counter,
  effect: SlotEffect.fadeScale | SlotEffect.blur,
  to: (ctx, val) => Text('$val'),
)

// Direction-aware animation:
AnimatedSlot<int>(
  connect: controller.counter,
  directionalEffect: DirectionalEffect.vertical,
  to: (ctx, val) => Text('$val'),
)
