+- DOM text renders exclusively from the embedded Windows/macOS/Linux/Android font bundles so layouts never fall through to host fonts on the underlying machine
 
 > **Implementation Detail:** Low‑level rendering paths in Skia (2D/Canvas) and HarfBuzz (text shaping) are tuned where needed to align metrics and glyph shaping across OS targets. We also apply targeted WebGL/WebGPU parameter controls to keep visual output stable across contexts.

 > **Professional-grade browser technology** through multi-layer fingerprint consistency, network-stack control, and automation-hardening.
 
-- **Multi‑Layer Consistency:** Canvas/WebGL/Text metrics with low‑level Skia/HarfBuzz tuning and targeted WebGL/WebGPU controls
-- **Clean Automation:** CDP/WebDriver hardening, Chrome‑like behavior, and framework‑less early hooks via `--bot-script`
-- **Configurability:** 30+ CLI overrides, per‑context proxies (ENT Tier1) with automatic geo‑detection, and session tools (cookies/bookmarks/title)
-- **Headless ↔ GUI Parity:** Stable GPU/WebGPU/media signals and consistent behavior across browser modes
-- **Performance Controls:** Precise FPS simulation, memory/storage timing, and GPU micro‑benchmarks for realistic profiles; runtime timing scaling (ENT Tier1) and deterministic noise seeds (ENT Tier2)
-- **Focus & Session Control:** Always-active tab emulation, configurable WebRTC ICE servers, and expanded media decoder reporting for authentic runtime signals
-- **Network & Proxy Enhancements:** Per-context proxies (ENT Tier1) with auto geo detection; UDP-over-SOCKS5 tunnel for QUIC/STUN in ENT Tier3; ICE presets optional when UDP is available
-> **Professional-grade browser technology** through sophisticated multi-layer fingerprint consistency and cross-platform compatibility systems
+- **Multi‑Layer Noise**: Canvas/WebGL/WebGPU/Text/Audiocontext surfaces share deterministic, cross-worker noise with low-level Skia/HarfBuzz tuning
+- **Automation Hardening**: CDP/WebDriver artifact scrubbing, framework-less `--bot-script`, and console suppression PRO toggles keep detectors blind
+- **Configurable Stack**: 30+ CLI overrides, ENT Tier1 per-context proxies with auto geo, and session tooling (cookies/bookmarks/title/history)
+- **Typography Fidelity**: DOM text renders from embedded Windows/macOS/Android font packs so host fonts never leak during cross-OS simulation
+- **Client Hints Lockstep**: DPR/device-memory/UA-CH headers match JavaScript-visible values for airtight CH vs JS parity
+- **Headless ↔ GUI Parity**: Identical GPU/WebGPU/media signals across browser modes for stable automation baselines
+- **Performance Controls**: Precision FPS/memory timings plus ENT Tier1 timing/seed controls for reproducible benchmarks
+- **Focus & Session Control**: Always-active tabs, configurable ICE presets, and expanded media reporting keep sessions believable
+- **Network Enhancements**: ENT Tier1 per-context proxies, UDP-over-SOCKS5 (ENT Tier3), and SOCKS5H DNS-in-tunnel behavior for clean geo signals
