RPS Simulator (v1.0.0)

The first production release of the RPS Simulator!

Features

Interactive Simulation: Watch entities move, collide, and transform according to classic Rock–Paper–Scissors rules.
Deterministic Seeding: Control simulation outcomes with a custom seed input; easily apply, randomize, or copy seeds.
Responsive Canvas: High-DPI support and auto-resizing keep the simulation sharp across devices.
Customizable Settings:
- Adjustable entity size and simulation speed.
- Configurable starting population per type.
- Two wall modes:
  - Bounce: Entities rebound off the edges like balls in a box.
  - Wraparound (toroidal): Entities leaving one edge reappear on the opposite edge, like in the game Asteroids.
Persistent Controls: Most settings are saved locally and restored on reload.
Visualization Tools:
- Real-time population mix bar with percentages.
- Sparkline chart showing population history over time (a compact line graph that shows trends at a glance).
Accessibility & Feedback:
- Clear labels and live-updating status indicators.
- Toast notifications (small popups at the bottom of the screen) for key actions such as applying seeds or declaring winners.

Optimized collision detection using a spatial grid (splits the space into cells for faster checks).
Velocity clamping and overlap resolution ensure stable physics behavior, avoiding runaway speeds or “stuck” entities.
Safeguards against excessive entities and overly long seeds to prevent slowdowns.
Graceful fallback for environments without localStorage, clipboard, or crypto support.
