Modern web app UI layout mockup for a visual prompt compiler (functional SaaS design targeting general creators), dark mode theme with sleek slate gray and deep obsidian panels. Premium, clean node-based graph editor interface with a high signal-to-noise ratio, strictly avoiding messy "spaghetti wire" visual complexity. The interface features three clean columns: 1. LEFT PANEL (Semantic Context): Features a prominent 'Beginner / Advanced Workflow' toggle at the top. Below are semantic context controls using clean, pill-shaped segmented buttons instead of numeric sliders (e.g., 'Magic: [None] [Low] [Active] [High]'). 2. CENTER WORKSPACE (The Semantic Graph): A structured, top-down directed graph layout. A root 'Core Concept' node branches elegantly into sibling nodes like 'Environment', 'Lighting', and 'Subject', indicating non-linear scene construction. The curved connecting lines (edges) between nodes display small '96% Match' confidence score badges to evaluate the relationship. Nodes feature a conversational 'Because you selected...' reasoning block and 1-click suggestion chips acting as autocomplete. A structured '+ Add Element' menu displays a controlled vocabulary list (Camera, Emotion, Style). 3. RIGHT PANEL (Compiled Output & Inspector): Features a compiled prompt text block with semantic syntax highlighting. Visualized bidirectional interactivity: a color-coded phrase in the text is being hovered over, triggering a bright glowing pulse effect on the corresponding node in the center graph to demonstrate real-time visual mapping. Minimalist sans-serif typography, flat UI design, distinct bright accent colors (neon blue, teal, purple) used for active states and semantic color-coding, highly spacious layout, professional creative software aesthetic mimicking high-end 3D or engine editors.
