Haptic Feedback

• Dual implementation: LuaJIT FFI (primary, zero-latency) + haptic.py (Python evdev fallback)
• Pulses on dial rotation

Notable Patterns

• No external Lua dependencies — JSON parser, animation utils, and haptic FFI are all inline in main.lua
• LÖVE threads used for non-blocking audio file loading (no AL thread starvation)
• gptokeyb as controller-to-keyboard bridge — all input comes as keypress events mapped through gptk configs
• Quit combo: L1 + R1 + L2 (1.5s window)
• Screen lock: R2 toggles, uses batocera-brightness for display off/on
