Decoded design system

Dagster's decoded design system: background #FFFFFF, text #030615, accent #4F43DD, link #FBFAFF, primary #1F2A37; type scale h1 64px / h2 48px / body 14px; 4px spacing base; 16px base radius. The single interactive/action color is #1B0130 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #1B0130 — the single interactive color; only on things you click or must notice, never large fills.
• accent #4F43DD — accent for emphasis — keep it rare on the page.
• primary #1F2A37 — a brand color — but the call-to-action uses #1B0130, not this.
• link #FBFAFF — 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 #030615 — 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.

# Dagster — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFF0F0` |
| border | `#D9D9DB` |
| text | `#030615` |
| text_muted | `#62646D` |
| primary | `#1F2A37` |
| accent | `#4F43DD` |
| link | `#FBFAFF` |
| secondary | `#030615` |
| button_bg | `#1B0130` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#1B0130` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#4F43DD` — accent for emphasis — keep it rare on the page.
- **primary** `#1F2A37` — a brand color — but the call-to-action uses #1B0130, not this.
- **link** `#FBFAFF` — 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** `#030615` — 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` 72.2% · `#080A19` 14.3% · `#5F667B` 9.6% · `#E5DDE4` 2.5%

## Typography

- Heading: **Geist**
- Body: **Geist**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 600 · lh 72px |
| h2 | 48px / 600 · lh 58px · tracking -0.16px |
| h3 | 40px / 600 · lh 40px · tracking 0.32px |
| body | 14px / 500 · lh 20px |

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

> **Fonts —** Geist — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 8px, 11px, 12px, 14px, 16px, 19px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 112px top/bottom padding per section (measured)

## Radius
- base: 16px
- button: 48px
- card: 8px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#1B0130` / `#FFFFFF` | none | 48px | 11.2px 19.2px 11.2px 19.2px | 600 14px | none |
| secondary | `#F9FAFB` / `#332AA6` | none | 8px 0px 0px 8px | 24px 0px 24px 24px | 400 16px | none |

**States (measured, not guessed)**

- primary focus: outline `2px solid rgb(77, 101, 255)`
- transition: `background-color 0.3s cubic-bezier(0.455, 0.03, 0.515, 0.955)`

## Shadows (elevation)
- subtle: `rgba(79, 67, 221, 0.05) 0px 1px 1px 0px`
- card: `rgba(79, 67, 221, 0.05) 0px 1px 2px 0px`
- overlay: `rgba(0, 0, 0, 0.05) 0px 12px 33px 3px`

## Motion
- durations: 250ms (dominant) · 200ms · 300ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: background-color, transform, color, box-shadow

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

_…and 108 more measured on the page._

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

## Layout (measured)
- container max 1200px · common grid: 4-col
- nav: 88px relative · bg rgba(255, 255, 255, 0)

## Motion choreography (measured)
Load order: `img.bg-home-header-left` @0ms → `img.bg-home-header-right` @286ms → `div.marquee_content-wrapper`×6 @286ms → `div.faq-icon`×5 @804ms → `div.faq-icon` @860ms → `div.faq_content`×5 @860ms
- `img.bg-home-header-left` — transform translateY(0px) scale(1)→translateY(0px) scale(1) — 8000ms ease-in-out · loops
- `img.bg-home-header-right` — transform translateY(0px) scale(1)→translateY(0px) scale(1) — 8500ms ease-in-out (delay 300ms) · loops
- scroll reveal: 1 elements rest at translateY(-87px), animate in over 8000ms (1 revealed during the drive).

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

## Components (measured)
- link: #000000 · no underline — hover #4F43DD

## Responsive (measured)
- breakpoints: 479px · 768px · 991px
- mobile (390px): hero 40px · 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.
