Decoded design system

Sentry's decoded design system: background #1F1633, text #FFFFFF, accent #6A5FC1, link #6A5FC1, primary #6A5FC1; type scale h1 88px / h2 60px / body 16px; 4px spacing base; 8px base radius. The single interactive/action color is #6A5FC1 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #6A5FC1 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #6A5FC1 — one role, not several (the action color).
• accent #6A5FC1 — 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 #FF45A8 — 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.

# Sentry — Design System

> dark, professional, medium, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#1F1633` |
| surface | `#2C233F` |
| border | `#403851` |
| text | `#FFFFFF` |
| text_muted | `#A9A6B1` |
| primary | `#6A5FC1` |
| accent | `#6A5FC1` |
| link | `#6A5FC1` |
| secondary | `#FF45A8` |
| button_bg | `#6A5FC1` |
| button_text | `#1F1633` |

**Using these colors**

- **Action color** `#6A5FC1` — 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 `#6A5FC1` — one role, not several (your action color).
- **accent** `#6A5FC1` — 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** `#FF45A8` — 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): `#1F1633` 71.5% · `#332258` 17.9% · `#8B6E99` 10.6%

## Typography

- Heading: **Dammit Sans** _(free fallback: Newsreader)_
- Body: **Rubik** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 88px / 700 · lh 106px |
| h2 | 60px / 500 · lh 66px |
| h3 | 30px / 400 · lh 36px |
| body | 16px / 400 · lh 24px |
| small | 15px / 500 · lh 21px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 8px, 12px, 16px, 20px, 24px, 32px, 36px, 40px — snap all gaps/padding to these
- section rhythm: 64px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 8px
- card: 8px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#1F1633` | 2px solid rgba(0, 0, 0, 0) | 8px | 12px 16px 12px 16px | 700 14px / 0.2px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | none | 8px | 12px 16px 12px 16px | 700 14px / 0.2px | none |

**States (measured, not guessed)**

- primary focus: background `#FFB287` · outline `2px solid rgb(79, 70, 229)`
- transition: `background-position 0.2s ease`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.08) 0px 2px 8px 0px`

## Motion
- durations: 200ms (dominant) · 800ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease-out`
- animated properties: transform, background-color, border-color, color

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

## Motion choreography (measured)
Load order: `span.animated` @0ms → `div.logo-row` @0ms → `img.rive-poster` @1652ms → `canvas.w-full` @1653ms
- scroll reveal: 5 elements rest at opacity 0, animate in over 0.3s cubic-bezier(0.4, 0, 0.2, 1) (0 revealed during the drive).

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

## Components (measured)
- card ×4: pad 0px 0px 0px 0px · r 12px · bg rgba(0, 0, 0, 0)
  - hover: font-weight `400` · letter-spacing `normal`
- link: #FFFFFF · underline

## Responsive (measured)
- breakpoints: 576px · 640px · 768px · 992px · 1152px
- mobile (390px): hero 50px · 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.
