## 3. Engineering Methodologies & Technical Tenets

1. **Zero-Latency In-Browser Performance**: Rather than relying on heavyweight frameworks, critical paths (game loops, rendering, physics, video playback) use direct WebGL, Canvas API, or WebAssembly (WASM).
2. **True Offline-First Architecture**: PWAs are designed so that the initial download provides the full runtime. Data is persisted to client-side storage (IndexedDB / OPFS) first, with graceful background synchronization.
3. **Local-First AI Economics**: Believes in deploying models to consumer hardware (4 GB - 16 GB VRAM) using INT4 quantization and efficient inference engines (vLLM, Ollama, GPTQ) to minimize cloud GPU hosting bills.
4. **Taste-Driven Polish & Accessibility**: Clean semantic HTML, fluid type scales, strict WCAG AA contrast ratios (>4.5:1), and zero decorative layout shifts.
