Decoded design system

Jitter's decoded design system: background #FFFFFF, text #19171C, accent #19171C, link #FFFFFF, primary #7A40ED; type scale h1 200px / h2 80px / body 18px; 4px spacing base; 17px base radius. The single interactive/action color is #19171C — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #19171C — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #19171C — one role, not several (the action color).
• accent #19171C — 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.
• primary #7A40ED — a brand color — but the call-to-action uses #19171C, not this.
• link #FFFFFF — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #FD3456 — 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.

# Jitter — Design System

> light, modern, high, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DCDCDC` |
| text | `#19171C` |
| text_muted | `#706F72` |
| primary | `#7A40ED` |
| accent | `#19171C` |
| link | `#FFFFFF` |
| secondary | `#FD3456` |
| button_bg | `#19171C` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#19171C` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#19171C` — one role, not several (your action color).
- **accent** `#19171C` — 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.
- **primary** `#7A40ED` — a brand color — but the call-to-action uses #19171C, not this.
- **link** `#FFFFFF` — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#FD3456` — 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): `#FFFFFF` 91.4% · `#F1F1F2` 2.5% · `#0B0A0D` 2.1% · `#A18DCD` 1.8%

## Typography

- Heading: **TWK Lausanne** _(free fallback: Newsreader)_
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 200px / 800 · lh 300px · tracking -6.4px |
| h2 | 80px / 800 · lh 72px · tracking -2.4px |
| h3 | 72px / 800 · lh 68px · tracking -3.2px |
| body | 18px / 600 · lh 18px · tracking -0.36px |
| small | 16px / 400 · lh 24px · tracking -0.35px |

- Weight ladder: 400 · 600 · 800 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** TWK Lausanne may be proprietary — safe free fallback: Newsreader (Google Fonts). Inter — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 3px, 4px, 5px, 8px, 10px, 12px, 20px, 30px, 40px, 44px — snap all gaps/padding to these
- section rhythm: 60px top/bottom padding per section (measured)

## Radius
- base: 17px
- button: 0px
- card: 40px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | none | 0px | 0px 0px 0px 0px | 600 18px / -0.36px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#19171C` | none | 0px | 0px 0px 0px 0px | 600 20px / -0.4px | none |

**States (measured, not guessed)**

- primary focus: outline `5px auto rgb(16, 16, 16)`

## Shadows (elevation)
- subtle: `rgb(255, 255, 255) 1px 0px 0px 0px, rgb(255, 255, 255) -1px 0px 0px 0px`
- card: `rgba(0, 0, 0, 0.01) 0px 63px 25px 0px, rgba(0, 0, 0, 0.05) 0px 35px 21px 0px, rgba(0, 0, 0, 0.09) 0px 16px 16px 0px, rgba(0, 0, 0, 0.1) 0px 4px 9px 0px`

## Motion
- durations: 300ms (dominant) · 500ms · 400ms
- easings: `cubic-bezier(0.25, 0.46, 0.45, 0.94)` (dominant) · `linear(0 0%, 0.255 1%, 0.4449 2%, 0.6018 3%, 0.7355 4%, 0.8513 5%, 0.9525 6%, 1.`
- animated properties: transform, opacity, color, border-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 |
|-------|-------|
| `--gradient-end-plain` | `#8D5DEF` |
| `--gradient-start-plain` | `#7A40ED` |
| `--virtual-scrollbar-width` | `0px` |

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

## Layout (measured)
- container max 860px · common grid: 10-col
- nav: 129px fixed

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|

## Motion choreography (measured)
Load order: `span._inner_ruopi_21` @0ms → `div._media_nzk6t_1` @0ms → `img._image_28ulh_1`×108 @474ms → `header._header_o7vm5_2` @530ms → `div._tagWrapper_kheb9_316` @1701ms → `div._tagWrapper_kheb9_316` @1701ms
- scroll reveal: 40 elements rest at opacity 0, translateY(-26px), animate in over 0.4s linear(0 0%, 0.255 1%, 0.4449 2%, 0.6018 3%, 0.7355 4%, 0.8513 5%, 0.9525 6%, 1.0413 7%, 1.1195 8%, 1.1881 9%, 1.24 (0 revealed during the drive).

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

## Components (measured)
- link: #19171C · no underline

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px
- mobile (390px): hero 64px · body 12px · 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.
