Modern web app UI layout mockup for a no-code visual prompt-builder website, dark mode theme with slate gray and obsidian panels. Figma and Notion UI design inspiration. Three-column interface: LEFT PANEL: Compact sidebar with horizontal segmented progress bars (Context Meters) and a minimal collapsible dependency tree with glowing connecting lines. CENTER WORKSPACE: A vertical generation pipeline of modular stacked cards connected by thin vertical lines (e.g., World, Theme, Environment). Cards feature minimal icons like locks (user-selected) and lightning bolts (auto-derived). RIGHT PANEL: A property inspector showing 'Chosen Because' visual tags above a dark compiled output preview box with a sleek action toolbar. Minimalist typography, clean spacing, subtle neon blue and teal accent highlights, high-resolution modern web design, clear vector icons.
