Slo generates continuous, high-quality brown noise specifically tuned for deep sleep and focus. Unlike looped recordings, Slo creates endless unique audio that never repeats. Does brown noise actually help you sleep? Yes. Studies show brown noise reduces the time to fall asleep and masks disruptive sounds like traffic, snoring, and noisy neighbors. Slo's deep-frequency brown noise is especially effective for light sleepers. What's the difference between brown noise, white noise, and pink noise? White noise contains all frequencies equally (like static). Pink noise emphasizes lower frequencies (like steady rain). Brown noise goes even deeper - like a rumbling waterfall or strong wind. Slo offers all three so you can find what works best for you. Can I use it for studying and focus? Absolutely. Many users prefer brown noise for deep work, studying, and ADHD focus. Slo's continuous playback helps maintain concentration for hours. Does it work offline? Yes. All sounds in Slo are generated on-device and work without an internet connection - perfect for flights, camping, or areas with no signal. Is Slo free? Slo offers free sounds with a timer. Premium unlocks the full sound library, mixing, and unlimited playback. Can I mix multiple sounds together? Yes. Slo lets you layer sounds - combine brown noise with rain, add thunder to white noise, or create your own custom soundscape with adjustable volumes. Does Slo have a sleep timer? Yes. Set a timer to automatically stop playback after you fall asleep - 15 minutes, 30 minutes, 1 hour, or custom duration. Is brown noise better than white noise for babies? Many parents find brown noise more soothing for babies because of its deeper, gentler frequency. Slo offers both so you can test which helps your baby sleep best.

# Design Brief: Editorial (with Minimal Monochrome)

Oversized serif headlines, narrow reading columns, and magazine-inspired grid layouts.

## Design Tokens

```css
:root {
  --background: #121212;
  --surface: #1e1e1e;
  --foreground: #f4f1eb;
  --muted-foreground: #8a857d;
  --accent: #e3a558;
  --radius: 16px;
  --font-heading: "Playfair Display", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #121212 (~68%) · Surface #1E1E1E (~12%) · Text #F4F1EB (~12%) · Muted Text #8A857D (~5%) · Accent #E3A558 (~3%). 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: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Pain Relief & Replacement
- Hero components: Large Hero Product Shot, Floating Multi-Cards
- Spatial layout notes: Split Copy & Visual hero structure paired with download app / install extension CTA and stacked avatars & testimonials.
- Visual summary: Editorial (Dark canvas, balanced density) featuring split copy & visual layout and product ui screenshot / component visuals.

## Avoid

- Generic SaaS hero templates
- Cramped multi-column feature grids
- Neon cyber accents

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.
