Third-party reviews & case dossiers
Acquisition breakdowns, engineer reviews & open-source metrics- What engineers like:
- Enables code to live where it belongs - alongside code (in Markdown). Auto-syncs as you refactor, rename, move code around. Comments on PRs when docs break. Supports Mermaid syntax for diagramming. IDE extensions (VS Code, JetBrains) reveal docs in-context with code. Editor supports dark mode.
- Trade-offs & limitations:
- Need to edit the docs using their editor (or the Markdown directly). In-IDE doc authoring is on the roadmap.
- Best suited for:
- Developers using VS Code or JetBrains should consider Swimm for in-context documentation

# Design Brief: Gradient Glow (with Editorial)
Luminous radial glows and translucent glass panels, widely used across modern AI products.
## Design Tokens
```css
:root {
--background: #f4f6fb;
--surface: #ffffff;
--foreground: #1a1a5c;
--muted-foreground: #5a6288;
--accent: #3d4fe0;
--radius: 8px;
--font-heading: "Source Serif 4", serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #F4F6FB (~42%) · Surface #FFFFFF (~12%) · Text #1A1A5C (~12%) · Muted Text #5A6288 (~8%) · Accent #3D4FE0 (~26%). 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: Light · 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: Book Demo / Contact Sales
- Headline hook: Pain Relief & Replacement
- Spatial layout notes: Split Copy & Visual hero structure paired with book demo / contact sales CTA and no explicit trust bar.
- Visual summary: Gradient Glow (Light canvas, airy density) featuring split copy & visual layout and 3d render / tactile object visuals.
## Avoid
- Muddy low-contrast text over gradients
- Overuse of full-screen rainbow backgrounds
- Cluttered dense tables in the hero
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.
