Comprehensive blueprint for a headless Raspberry Pi 3B projection mapping appliance: - Unified installer with 2GB swap safety for C++ source builds. - WebSocket-driven real-time vertex/surface manipulation. - 5-tab responsive dashboard (Dashboard, Mapping, Media, Network, System). - Media validation with ffprobe (H.264 check) and resource warnings. - Throttled log streaming and explicit mapping persistence.
