Marketing moves
Launches, search & content, referrals, promotions- I have Claude Ultra, almost 10% usage after ~10 minutes of performance work. Wonder if there's a future where most are priced out of SOTA models.

- Not Liquid Glass coming to an @andocorporation near you! _UILiquidLensView is a private API which you're not allowed to use, so I reimplemented it with Metal shaders. :)

# Design Brief: Minimal Monochrome (with Editorial)
Monochrome palette with a single accent color, hairline dividers, and generous whitespace.
## Design Tokens
```css
:root {
--background: #fafafa;
--surface: #ffffff;
--foreground: #0a0a0a;
--muted-foreground: #777777;
--accent: #148cdc;
--radius: 8px;
--font-heading: "Instrument Serif", serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FAFAFA (~78%) · Surface #FFFFFF (~13%) · Text #0A0A0A (~4%) · Muted Text #777777 (~4%) · Accent #148CDC (~1%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Centered Headline + CTA
- 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: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Pain Relief & Replacement
- Hero components: Custom Illustration, Floating Multi-Cards
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and stacked avatars & testimonials.
- Visual summary: Minimal Monochrome (Light canvas, airy density) featuring centered headline + cta layout and illustration / character art 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.
