Post excerpt:
We built Procaptcha to make sure there's an actually good alternative to Google's ReCAPTCHA that's not a complete nightmare for the end user. Crucially we're not just a giant ad network like almost all CAPTCHA providers [1]. Like with other CAPTCHA providers it's simple to set up, you just change a couple of tags [2]. We've got a few different CAPTCHA types

# Design Brief: Gradient Glow (with Enterprise Clean)

Luminous radial glows and translucent glass panels, widely used across modern AI products.

## Design Tokens

```css
:root {
  --background: #141025;
  --surface: #252041;
  --foreground: #f1eff5;
  --muted-foreground: #a8a3b9;
  --accent: #ed3781;
  --radius: 8px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #141025 (~64%) · Surface #252041 (~24%) · Text #F1EFF5 (~5%) · Muted Text #A8A3B9 (~5%) · Accent #ED3781 (~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 · Balanced
- Border radius & elevation: Medium Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Book Demo / Contact Sales · Trust bar uses Customer / Press Logo Strip
- Headline hook: Pain Relief & Replacement
- Hero components: Large Hero Product Shot, Customer Logo Wall
- Spatial layout notes: Split Copy & Visual hero structure paired with book demo / contact sales CTA and customer / press logo strip.
- Visual summary: Gradient Glow (Dark canvas, balanced density) featuring split copy & visual layout and product ui screenshot / component 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.
