# Design Brief: Minimal Monochrome (with 3D Tactile)
Monochrome palette with a single accent color, hairline dividers, and generous whitespace.
## Design Tokens
```css
:root {
--background: #1c1d26;
--surface: #272833;
--foreground: #ffffff;
--muted-foreground: #a7a8b0;
--accent: #c3a47e;
--radius: 8px;
--font-heading: "Roboto", ui-sans-serif, system-ui, sans-serif;
--font-body: "Roboto", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #1C1D26 (~81%) · Surface #272833 (~7%) · Text #FFFFFF (~6%) · Muted Text #A7A8B0 (~4%) · Accent #C3A47E (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Split Copy & Visual
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Airy
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: 3D Render / Tactile Object
- Conversion CTA: Download App / Install Extension
- Headline hook: Category Positioning Anchor
- Spatial layout notes: Split Copy & Visual hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: Minimal Monochrome (Dark canvas, airy density) featuring split copy & visual layout and 3d render / tactile object visuals.
## Avoid
- Multi-stop neon gradients
- Heavy drop shadows
- More than one competing accent color
Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
