📚 Guides & Technical Documentation

1. FLUX.2 & Klein 9B RefMods: Architecture, Extraction, and Usage Guide
   The primary comprehensive architectural handbook covering:

   • Theoretical underpinnings of 2D RoPE reference latent injection vs legacy pixel encoding
   • Where to find and download 1,400+ pre-extracted RefMods on Hugging Face (malcolmrey/klein9 & malcolmrey/browser)
   • Installing and configuring the ComfyUI-Flux2Klein9Mod custom node
   • Detailed breakdown of both official ComfyUI JSON workflows (workflow_klein9_refmod.json & workflow_klein9_refmod_lora.json)
   • Step-by-step RefMod creation with dataset curation best practices and CLI extraction

2. Visual Benchmarks & 5-Column Comparison Studies
   Detailed empirical evaluations across 6 celebrity benchmark datasets:

   • Embedded 5-column comparison grids for all benchmark subjects (Brett Cooper, Alison Brie, Olivia Wilde, Jodie Foster, Rebecca Ferguson, Sydney Sweeney)
   • Direct download links to individual model weights (.safetensors) on Hugging Face
   • High-resolution single run artifact links (examples/) for Pure LoRA, 8-Raw Reference, Pure RefMod, and Hybrid stacks
   • Computational throughput, token load, and VRAM scaling breakdowns
