Korean Steam Sauna Portrait - BloomGirls & Krea 2 Turbo

1. ARCHITECTURAL REASONING & COMPOSITION GEOMETRY: Deconstructs high-humidity ambient lighting and delicate East Asian facial geometry within diffusion latents. Steamy sauna environments with airborne vapor mist and warm backlight typically lead to lost micro-contrast or distorted skin gloss when rendered naively. Chaining BloomGirls UltraRealism (v1.0, trigger bl00m, weight 0.8) with Famegrid Natural Realism (weight 0.7) stabilizes delicate facial proportions and translucent glass skin while preventing over-smoothed plastic artifacts. Grounding the subject in a clean white waffle-cotton spa robe provides high-frequency textile micro-geometry, separating foreground latents cleanly from ambient cedar wood background tones. 2. CABLE ROUTING & SIGNAL TOPOLOGY: Sequential two-stage LoRA injection architecture feeding from Krea 2 Turbo INT8 UNET (krea2_turbo_int8_convrot.safetensors) and dedicated Qwen3-VL 4B text encoder (qwen3vl_4b_fp8_scaled.safetensors). The first stage applies BloomGirls to guide facial geometry and East Asian aesthetic conditioning; the second stage injects Famegrid to anchor natural pore detail and specular rim light gradients. Conditioning routes directly into a single deterministic positive conditioning node wired straight to KSampler, enforcing the WYSIWYG single-node invariant with zero standby nodes. Latents are decoded through the native 16-channel qwen_image_vae.safetensors. 3. HARDWARE BENCHMARKS & CONSUMER GPU FOOTPRINT: Synthesized and benchmarked on host NVIDIA GeForce RTX 4070 (12GB VRAM, CUDA 12.4). Peak VRAM consumption maintained at 4.2 GB during the 10-step Euler sampling at 832x1248 resolution. Total generation latency clocked at 111.7 seconds with zero host RAM offloading, confirming fluid viability across 8GB and 12GB consumer GPUs.
