daynight2d runtime foundation

Time subsystem
  -> Calendar state
  -> Schedule assets
  -> Routine components
  -> Timed behavior
  -> Optional visuals
  -> Replicated state

Reusable systems

Not tied to farming, shops, or NPCs.

Use the base classes to build growth, respawn, timed doors, enemy windows, festivals, crafting timers, puzzle timing, seasonal behavior, and project-specific systems.

Blueprint-first

Create child Blueprints from reusable components and bind to time, schedule, routine, and timed behavior events.

Optimized runtime

The core clock uses timers and events instead of per-frame ticking. Components stay tick-disabled by default.

2D-friendly visuals

Visuals are optional and do not force post process, dynamic lights, or 3D shadows.
