Decoded design system

Northflank's decoded design system: background #03060E, text #CDD5DF, accent #0A2820, link #697586, primary #CDD5DF; type scale h1 56px / h2 32px / body 14px; 8px spacing base; 2px base radius. The single interactive/action color is #0A2820 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0A2820 — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #0A2820 — one role, not several (the action color).
• accent #0A2820 — 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 #CDD5DF — ≈ the text color — a foreground/text color, not an action color (action = #0A2820).
• link #697586 — reads as a neutral UI color, not a link accent — verify against the reference (action = #0A2820).
• secondary #202939 — 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.

## Colors

| Role | Value |
|------|-------|
| bg | `#03060E` |
| surface | `#0F121A` |
| border | `#21252D` |
| text | `#CDD5DF` |
| text_muted | `#80868F` |
| primary | `#CDD5DF` |

**Using these colors**

- **Action color** `#0A2820` — 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 `#0A2820` — one role, not several (your action color).
- **accent** `#0A2820` — 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** `#CDD5DF` — ≈ the text color — a foreground/text color, not an action color (action = #0A2820).
- **link** `#697586` — reads as a neutral UI color, not a link accent — verify against the reference (action = #0A2820).
- **secondary** `#202939` — 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): `#03060E` 73.2% · `#0E1C27` 19.7% · `#344750` 7.1%

## Typography

- Heading: **Inter**
- Body: **Inter**
- Mono: **JetBrains Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 56px / 600 · lh 67px |
| h2 | 32px / 500 · lh 38px |
| h3 | 24px / 500 · lh 29px |
| body | 14px / 400 · lh 20px |
| small | 13px / 400 · lh 18px |
| eyebrow | 9px / 500 · tracking 2.07px |

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

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 6px, 8px, 10px, 12px, 15px, 16px, 20px, 24px, 32px, 40px — snap all gaps/padding to these
- section rhythm: 64px top/bottom padding per section (measured)

## Radius
- base: 2px
- button: 2px
- card: 6px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#EEF2F6` | 1px solid rgb(32, 41, 57) | 2px | 0px 0px 0px 0px | 400 14px | none |
| secondary | `rgba(45, 216, 129, 0.16)` / `#2DD881` | 1px solid rgba(45, 216, 129, 0.35) | 2px | 0px 0px 0px 0px | 400 16px | none |

**States (measured, not guessed)**

- primary hover: border `1px solid rgba(0, 0, 0, 0)` · background `#121926`
- primary focus: border `1px solid rgba(0, 0, 0, 0)` · background `#121926` · outline `2px solid rgba(45, 216, 129, 0.75)`
- transition: `border-color 0.2s cubic-bezier(0.165, 0.84, 0.44, 1)`

## Shadows (elevation)
- card: `rgba(3, 6, 14, 0.5) 0px 4px 7px 0px`
- overlay: `rgba(1, 178, 225, 0.1) -16px -16px 32px -8px`

## Motion
- durations: 200ms (dominant) · 300ms · 400ms
- easings: `ease` (dominant) · `cubic-bezier(0.165, 0.84, 0.44, 1)`
- animated properties: color, opacity, border-color, background-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`×5 @0ms → `a`×6 @256ms → `div` @588ms → `path`×24 @589ms → `path`×27 @589ms → `div` @828ms
- `span` ×5 — opacity 0→0 · transform scale(1)→scale(2) — 20000ms ease-out (delay -16000ms) · loops
- stagger: `span` ×5 — 4000ms apart
- scroll reveal: 11 elements rest at opacity 0, animate in over 0.4s cubic-bezier(0.165, 0.84, 0.44, 1) (0 revealed during the drive).

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

## Components (measured)
- card ×8: pad 20px 24px 20px 24px · r 0px · bg #070915
  - hover: font-weight `400` · letter-spacing `normal`
- link: #2DD881 · no underline
- disabled: bg rgba(0, 0, 0, 0) · text #CDD5DF

## Responsive (measured)
- breakpoints: 600px · 620px · 768px · 820px · 880px · 960px
- mobile (390px): hero 36px · body 17px · 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.
