FLSampler (BSS) for ComfyUI 🔬
A high-performance custom sampler inspired by the physiology of human sight (**Foveated Vision**). Engineered to deliver stunning cinematic clarity, rich micro-textures (skin, hair, fabrics), and precise depth-of-detail control inside the latent space—with zero performance overhead.
> âš¡ Ultimate Speed & Quality Combo:
> To achieve the ultimate balance of breathtaking visual clarity and extreme speed, we highly recommend pairing this node with our optimization suite ANIMA_BOOSTER

🔬 How it Works
Instead of uniform denoising, FLSampler selectively enhances latent focus zones:
Differential Latent Analysis: Dynamically tracks where structures and object boundaries are forming.
Local Contrast (Sharpness Boost): Unsharp-masks active focus zones directly in latent space for ultra-sharp details (safe default 0.5, range 0.0–3.0).
Stochastic Texture Injection: Adds controlled micro-noise to focus areas, naturally resolving into skin pores, clothing fabrics, wood grains, or hair, preventing flat plastic surfaces.
BSS Premium UI: Integrated dark-matte & gold custom theme.

Description
### What's New in v1.3.0 (BSS Premium Update):
* Gorgeous Premium UI: A sleek dark-matte & gold design theme that perfectly matches the high-end ANIMA Booster aesthetic.
* Isolated Slider Controls: Smooth interactive sliders with precise decimal rounding are now strictly dedicated to key FLS parameters fovea_strength, sharpness, mask_inertia).
* Elegantly Streamlined Inputs: Standard parameters like cfg and denoise are now rendered as high-end numeric input fields instead of bulky sliders.
* Anti-Frying Presets: Fine-tuned the default sharpness to a much safer 0.5 (down from 2.0 which was frying generations) and reduced maximum limits to optimal ranges (Fovea max to 10.0, Sharpness max to 3.0).
* Clean Workspace Name: Renamed the node display title to FLSampler (BSS).
