Decoded design system

Deno's decoded design system: background #FFFFFF, text #000000, accent #70FFAF, link #868789, primary #70FFAF; type scale h1 72px / h2 44px / body 18px; 4px spacing base; 4px base radius. The single interactive/action color is #F5F5F5 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F5F5F5 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #70FFAF — one role, not several (the action color).
• accent #70FFAF — accent for emphasis — keep it rare on the page.
• link #868789 — reads as a neutral UI color, not a link accent — verify against the reference (action = #F5F5F5).
• secondary #0A0E1C — 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.

# Deno — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#70FFAF` |
| accent | `#70FFAF` |
| link | `#868789` |
| secondary | `#0A0E1C` |
| button_bg | `#F5F5F5` |
| button_text | `#9EA0A5` |

**Using these colors**

- **Action color** `#F5F5F5` — 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` are all `#70FFAF` — one role, not several.
- **accent** `#70FFAF` — accent for emphasis — keep it rare on the page.
- **link** `#868789` — reads as a neutral UI color, not a link accent — verify against the reference (action = #F5F5F5).
- **secondary** `#0A0E1C` — 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): `#122125` 69.9% · `#FFFFFF` 16% · `#9BF4C3` 10% · `#2F413F` 4.1%

## Typography

- Heading: **Inter**
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 72px / 700 · lh 79px · tracking -1.8px |
| h2 | 44px / 700 · lh 48px · tracking -1.1px |
| h3 | 36px / 700 · lh 40px · tracking -0.9px |
| body | 18px / 400 · lh 28px |
| small | 16px / 400 · lh 24px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 3px, 4px, 6px, 8px, 10px, 12px, 16px, 24px, 32px — snap all gaps/padding to these

## Radius
- base: 4px
- button: 0px
- card: 4px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F5F5F5` / `#9EA0A5` | none | 0px | 6px 16px 6px 16px | 400 12px | none |
| secondary | `#25272B` / `#000000` | none | 9999px | 2px 2px 2px 2px | 400 16px | none |

**States (measured, not guessed)**

- primary hover: color `#56575A`
- primary focus: outline `2px solid rgb(174, 1, 255)`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 1ms · 800ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease-out`
- animated properties: color, background-color, border-color, outline-color

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

- `img.absolute` — transform translateY(128px)→translateY(0px) — 1ms ease-out
- `h2.text-balance` ×2 — opacity 0→1 · transform translateY(16px)→translateY(0px) — 800ms cubic-bezier(0.075, 0.82, 0.165, 1)
- `a.absolute` — opacity 0→1 · transform translateX(-30px)→none — 1ms ease-out
- stagger: `div` ×9 — 80ms apart
- scroll reveal: 6 elements rest at opacity 0, translateY(16px), animate in over 0.15s cubic-bezier(0.4, 0, 0.2, 1) (5 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

## Responsive (measured)
- breakpoints: 440px · 640px · 768px · 1024px · 1280px · 1536px

## 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.
