perf(#873): implement Three.js LOD and texture optimization

- Agent orbs: THREE.LOD with 3 detail levels (32/16/8 segments)
- Halo geometry: reduced from 64 to 24 segments
- Particle systems: LOD-aware counts (500-1500 based on tier)
- Agent label texture cache: reuse textures across agents
- Stats.js integration for performance monitoring
- Document minimum sovereign hardware requirements

+# Three.js LOD and Texture Audit — Issue #873
+
+## Audit Summary
+
+**Date:** 2026-04-13
+**Issue:** #873 — Three.js LOD and Texture Audit for Local Hardware
+**Target:** 60fps on base M1 Mac (8-core CPU, 7-core GPU, 8GB RAM)
+
+## Changes Made
+
+### 1. Agent LOD Implementation
+
+**Before:** All agent orbs used `SphereGeometry(0.4, 32, 32)` regardless of distance.
+**After:** Implemented `THREE.LOD` with three detail levels:
+
+| Distance | Geometry | Segments | Triangles |
+|----------|----------|----------|-----------|
+| 0-15 units | High | 32x32 | ~2,048 |
+| 15-30 units | Medium | 16x16 | ~512 |
+| 30+ units | Low | 8x8 | ~128 |
+
+**Impact:** ~75% triangle reduction for distant agents (4 agents × 3 levels).
+
+### 2. Halo Geometry Optimization
+
+**Before:** `TorusGeometry(0.6, 0.02, 16, 64)` — 64 segments
+**After:** Reduced to 24 segments (12 on low-tier)
+
+**Impact:** ~62% vertex reduction per halo.
+
+### 3. Agent Label Texture Cache
+
+**Before:** Each agent created its own CanvasTexture.
+**After:** Implemented texture cache keyed by `name_color`. Reuses textures for agents with same name/color.
+
+**Impact:** Reduced texture memory and GPU uploads.
+
+### 4. Particle System LOD
+
+| Tier | Main Particles | Dust Particles | Total |
+|------|----------------|----------------|-------|
+| High | 1,500 | 500 | 2,000 |
+| Medium | 1,000 | 300 | 1,300 |
+| Low | 500 | 150 | 650 |
+
+**Impact:** 67% particle reduction on low-tier hardware.
+
+### 5. Post-Processing Tiering
+
+| Setting | High | Medium | Low |
+|---------|------|--------|-----|
+| Bloom Strength | 0.6 | 0.35 | 0.35 |
+| Shadow Map | 2048px | 1024px | 512px |
+| Pixel Ratio | 2x | devicePR | 1x |
+
+### 6. Stats.js Integration
+
+Added `three/addons/libs/stats.module.js` for real-time performance monitoring.
+
+**Access:** `window.stats` in browser console. Shows FPS, render time, and draw calls.
+
+## Minimum Sovereign Hardware Requirements
+
+### Tier: Low (Target: 30fps)
+- **CPU:** 4+ cores (Intel i5 / Apple M1 / AMD Ryzen 3)
+- **GPU:** Integrated (Intel UHD 630 / Apple M1)
+- **RAM:** 4GB
+- **Browser:** Chrome 90+, Firefox 88+, Safari 15+
+
+### Tier: Medium (Target: 45fps)
+- **CPU:** 6+ cores (Intel i7 / Apple M1 Pro / AMD Ryzen 5)
+- **GPU:** Entry discrete (GTX 1050 / Apple M1 Pro 14-core)
+- **RAM:** 8GB
+- **Browser:** Latest versions
+
+### Tier: High (Target: 60fps)
+- **CPU:** 8+ cores (Intel i9 / Apple M1 Max / AMD Ryzen 7)
+- **GPU:** Mid-range discrete (RTX 3060 / Apple M1 Max 24-core)
+- **RAM:** 16GB
+- **Browser:** Latest versions
+
+## Performance Validation Checklist
+
+- [ ] Stats.js overlay showing 60fps with 5+ agents
+- [ ] Draw calls < 100 per frame
+- [ ] Triangle count < 500k per frame
+- [ ] Texture memory < 256MB
+- [ ] No frame spikes > 16.6ms (60fps budget)
+
+## Future Optimizations
+
+1. **Instanced Rendering:** Use `InstancedMesh` for repeated geometries (portals, runestones)
+2. **Texture Atlasing:** Combine agent label textures into single atlas
+3. **Basis/KTX2:** Compress textures with Basis Universal
+4. **WebGL2 Compute:** Offload particle updates to compute shaders
+5. **Occlusion Culling:** Implement for interior spaces
