Decoded design system

Doppler's decoded design system: background #1C1624, text #000000, accent #00F575, link #00F575, primary #00F575; type scale h1 96px / h2 64px / body 14px; 8px spacing base; 12px base radius. The single interactive/action color is #00F575 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #00F575 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #00F575 — one role, not several (the action color).
• accent #00F575 — 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.
• secondary #F55C15 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Doppler — Design System

> dark, modern, high, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#1C1624` |
| surface | `#1A1421` |
| border | `#17121E` |
| text | `#000000` |
| text_muted | `#0A080D` |
| primary | `#00F575` |
| accent | `#00F575` |
| link | `#00F575` |
| secondary | `#F55C15` |
| button_bg | `#00F575` |
| button_text | `#1C1624` |

**Using these colors**

- **Action color** `#00F575` — 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 `#00F575` — one role, not several (your action color).
- **accent** `#00F575` — 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.
- **secondary** `#F55C15` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#1C1624` 90.3% · `#39474A` 9.7%

## Typography

- Heading: **__DopplerRepro_a18e76** _(free fallback: Newsreader)_
- Body: **__DopplerRepro_a18e76** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 96px / 450 · lh 101px · tracking -1.92px |
| h2 | 64px / 450 · lh 74px · tracking -1.28px |
| h3 | 48px / 450 · lh 58px · tracking -0.96px |
| body | 14px / 500 · lh 17px |
| small | 12px / 400 · lh 12px · tracking 0.36px |
| eyebrow | 10px / 700 · tracking 1px |

- Weight ladder: 400 · 450 · 500 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** __DopplerRepro_a18e76 may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 8px, 10px, 14px, 16px, 20px, 28px, 32px, 40px, 56px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 20px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#00F575` / `#1C1624` | none | 12px | 10px 16px 10px 16px | 400 16px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#D0C9C4` | none | 12px | 8px 8px 8px 8px | 700 15px / 0.15px | none |

**States (measured, not guessed)**

- primary hover: background `#00BF5B`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: color `#F1F0EC`
- transition: `color 0.3s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.45) 0px 8px 30px 0px`

## Motion
- durations: 300ms (dominant) · 400ms · 150ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0.8, 0.01, 0.11, 0.9)`
- animated properties: color, background-color, border-color, text-decoration-color

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

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--global-ease` | `cubic-bezier(0.9,0.1,0.1,0.9)` |

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- nav: 72px · border-bottom 1px solid rgb(85, 80, 91) · bg #1C1624

## Motion choreography (measured)
Load order: `div.rfm-marquee`×2 @0ms
- scroll reveal: 12 elements rest at opacity 0, translateY(60px), animate in over 0.4s cubic-bezier(0.4, 0, 0.2, 1) (1 revealed during the drive).

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #00F575 · no underline

## Responsive (measured)
- breakpoints: 975px · 1290px
- mobile (390px): hero 36px · body 16px · nav: hamburger

## 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.
