Tokens

Pocket Casts Mobile's decoded design system: background #000000, text #FFFFFF, accent #FF3401, link #FF3401, primary #FF3401; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #FF3401 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FF3401 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #FF3401 — one role, not several (the action color).
• accent #FF3401 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.

# Pocket Casts Mobile — Design System

> dark, consumer, high — deep decode (measured live)

Pocket Casts Mobile — palette measured from official store listing screenshots (colors only; no font claims). Type scale shown is the platform HIG default.

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#0F0F0F` |
| border | `#262626` |
| text | `#FFFFFF` |
| text_muted | `#9E9E9E` |
| primary | `#FF3401` |
| accent | `#FF3401` |
| link | `#FF3401` |
| button_bg | `#FF3401` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#FF3401` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link`, `button_bg` are all `#FF3401` — one role, not several (your action color).
- **accent** `#FF3401` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 30.1% · `#270707` 28.5% · `#F1F1F1` 16.5% · `#9F595C` 12.4%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 700 · lh 74px · tracking -1.28px |
| h2 | 53px / 700 · lh 61px · tracking -1.06px |
| h3 | 39px / 700 · lh 45px |
| body | 22px / 300 · lh 32px |
| small | 18px / 400 · lh 26px |

- Weight ladder: 300 · 400 · 500 · 700 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 8px, 10px, 12px, 13px, 16px, 18px, 20px, 24px, 30px — snap all gaps/padding to these
- section rhythm: 80px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 12px
- card: 4px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#333333` | 1px solid rgb(224, 224, 224) | 4px | 10px 10px 10px 10px | 400 16px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#292B2E` | 1px solid rgb(41, 43, 46) | 8px | 13.44px 16px 13.44px 16px | 500 16px | none |

**States (measured, not guessed)**

- primary focus: outline `2px solid rgb(24, 122, 220)`

## Motion
- durations: 200ms (dominant) · 50ms · 300ms
- easings: `ease` (dominant) · `ease-in-out`
- animated properties: transform, opacity, background, color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
