## Architectural & Systems Analysis
From a mobile SoC, thermal envelope, and embedded Linux standpoint, this Steam Deck milestone highlights:

- **Dynamic Power Scaling (TDP Control):** Fine-grained APU clock gating allows sustained 3-8 hour battery life on indie workloads.
- **Gamescope Compositor Integration:** Micro-compositor isolation guarantees frame-pacing stability and system-level FSR (FidelityFX Super Resolution).
- **Immutable Root Filesystem:** A/B partition updates ensure bulletproof system integrity even after catastrophic battery exhaustion.

## Impact on the Open Ecosystem
Demonstrates that consumer hardware built on an open Linux kernel can compete directly with closed handheld ecosystems.
