Input buffer system:
- Added 3-slot direction input buffer to handle rapid key presses
- Buffer ignores duplicate inputs (same key pressed multiple times)
- Opposite direction replaces last buffered input (e.g., LEFT→RIGHT replaces LEFT)
- Buffer overflow replaces last slot when full
- Multi-segment snakes skip invalid 180° turns when consuming buffer
- Head-only snakes (length=1) can turn 180° for flexibility
Gameplay improvements:
- Desktop client auto-starts game on connect (no SPACE needed)
- Field populates with 3 apples when no players connected
- HTTP server now binds to 0.0.0.0 for network access (matches game server)
Testing:
- Added 7 new tests for input buffer functionality
- Added test for zero-player apple spawning
- All 19 tests passing

Major gameplay changes:
- Snakes no longer die from collisions
- When blocked, snakes get "stuck" - head stays in place, tail shrinks by 1 per tick
- Snakes auto-unstick when obstacle clears (other snakes move/shrink away)
- Minimum snake length is 1 (head-only)
- Game runs continuously without rounds or game-over state
Color system:
- Each player gets a persistent color for their entire connection
- Colors assigned on join, rotate through available colors
- Color follows player even after disconnect/reconnect
- Works for both desktop and web clients
Display improvements:
- Show snake length instead of score
- Length accurately reflects current snake size
- Updates in real-time as snakes grow/shrink
Server fixes:
- Fixed HTTP server initialization issues
- Changed default host to 0.0.0.0 for network multiplayer
- Improved file serving with proper routing
Testing:
- Updated all collision tests for stuck mechanics
- Added tests for stuck/unstick behavior
- Added tests for color persistence
- All 12 tests passing

Implemented a complete network multiplayer Snake game with the following features:
Core Game:
- Client-server architecture using asyncio for networking
- Pygame-based rendering at 60 FPS
- Server-authoritative game state with 10 TPS
- Collision detection (walls, self, other players)
- Food spawning and score tracking
- Support for multiple players with color-coded snakes
Server Discovery:
- UDP multicast-based automatic server discovery (239.255.0.1:9999)
- Server beacon broadcasts presence every 2 seconds
- Client discovery with 3-second timeout
- Server selection UI for multiple servers
- Auto-connect for single server
- Graceful fallback to manual connection
Project Structure:
- src/shared/ - Protocol, models, constants, discovery utilities
- src/server/ - Game server, game logic, server beacon
- src/client/ - Game client, renderer, discovery, server selector
- tests/ - Unit tests for game logic, models, and discovery
Command-line interface with argparse for both server and client.
