- **Primary text (`#ffffff`)** — uses `ink` token
- **Secondary text (`#b3b3b3`)** — uses `ink-soft` token
- **Accent (`#1ed760`)** — uses `accent` token
- **Muted (`#7c7c7c`)** — uses `muted` token
- **Borders (`rgba(255,255,255,0.1)`)** — uses `line` token

## Typography

- **Display:** geometric-sans
- **Body:** geometric-sans

- Use bold weight for primary titles and section headers.
- Use regular weight for body text and navigation items.
- Maintain tight line-heights for vertical density.

## Layout

Fixed left sidebar (~280px) with a fluid main content area.

*Rhythm:* 8px base rhythm with 12px and 24px increments for content gaps.

## Elevation & Depth

- rgba(0,0,0,0.3) 0px 8px 8px 0px

- `md`: 8px
- `lg`: 12px
- `pill`: 999px

## Components

- **button:** Pill-shaped solid buttons with high contrast or low-emphasis outlines.
- **card:** Flat, hoverable content cards with prominent artwork and minimal padding.
- **chip:** None clearly visible in the current view.
- **input:** Rounded search bar with a subtle dark background and left-aligned icon.
- **hero:** Grid-based sections for trending content and artists.

## Do's and Don'ts

**Don't:**
- Don't use light backgrounds — screenshot shows a dark (#121212) environment.
- Don't use serif fonts — screenshot shows a geometric sans-serif typeface.
- Don't use sharp corners on primary buttons — screenshot shows pill-shaped (999px) buttons.
- Don't use excessive drop shadows — screenshot uses only subtle, dark shadows for elevation.
- Don't use a multi-column layout for navigation — screenshot shows a fixed sidebar.
- Don't use bright, multi-colored UI accents — screenshot uses a single green (#1ed760) for active states.

## System Prompt (paste into AI agent)

```
Design a music streaming platform UI that is content-focused and immersive. Use a dark color palette dominated by #121212 and #1f1f1f, with white (#ffffff) for primary text and #b3b3b3 for secondary text. The signature accent is #1ed760. Typography should use a clean geometric sans-serif. Layout should follow a sidebar-plus-content structure. Critical constraints: never use light backgrounds, never use serif fonts, and keep interactive elements pill-shaped or rounded.
