Neon — Design System

dark · modern · medium · tailwind · confidence 92% · deep decode

Neon puts Postgres on a black stage lit by its own green glow: Inter at 68px/400 does the talking without display-font theatrics, 4px-radius buttons stay quiet, and branching diagrams plus autoscaling charts carry the story. The single neon accent against the dark reads as the brand itself — database engineering with just one light on.

Tokens

Neon's decoded design system: background #000000, text #ECECEE, accent #34D59A, link #39A57D, primary #34D59A; type scale h1 68px / h2 48px / body 16px; 4px spacing base; 4px base radius. The single interactive/action color is #34D59A — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Neon — Design System

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

Neon puts Postgres on a black stage lit by its own green glow: Inter at 68px/400 does the talking without display-font theatrics, 4px-radius buttons stay quiet, and branching diagrams plus autoscaling charts carry the story. The single neon accent against the dark reads as the brand itself — database engineering with just one light on.

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#0E0E0E` |
| border | `#232323` |
| text | `#ECECEE` |
| text_muted | `#929293` |
| primary | `#34D59A` |
| accent | `#34D59A` |
| link | `#39A57D` |
| button_bg | `#34D59A` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#34D59A` — 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`, `button_bg` are all `#34D59A` — one role, not several (your action color).
- **accent** `#34D59A` — 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.
- **link** `#39A57D` — inline text links and link-styled controls.
- **Page coverage** (full-page screenshot pixels): `#010101` 73.8% · `#0D1413` 19.4% · `#5C6C67` 6.8%

## Typography

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

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 72px / 400 · lh 81px · tracking -2.88px |
| h2 | 48px / 400 · lh 54px · tracking -1.92px |
| h3 | 24px / 500 · lh 24px · tracking -0.96px |
| body | 16px / 400 · lh 24px · tracking -0.32px |
| small | 15px / 400 · lh 23px · tracking -0.15px |

- Weight ladder: 300 · 400 · 500 · 600 — 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: 4px, 6px, 8px, 10px, 12px, 14px, 16px, 18px, 24px, 25px — snap all gaps/padding to these
- section rhythm: 160px top/bottom padding per section (measured)

## Radius
- base: 4px
- button: 9999px
- card: 4px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#000000` | none | 3.35544e+07px | 0px 18px 0px 18px | 500 14px / -0.28px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#94979E` | none | 4px | 12px 4px 12px 4px | 400 13px / -0.13px | none |

**States (measured, not guessed)**

- primary hover: background `#C9CBCF`
- primary focus: outline `2px solid rgb(56, 165, 125)`
- transition: `color 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 200ms (dominant) · 150ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `linear`
- 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.

## Layout (measured)
- container max 1600px · common grid: 2-col
- nav: 64px sticky · bg #000000

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

| 3934 | 1312 | 2 | 128 | 160/240 | 18/82 |

## Motion choreography (measured)
Load order: `span.truncate` @0ms → `ul.logos-content`×4 @0ms → `div.transition-opacity` @797ms
- scroll reveal: 6 elements rest at opacity 0, animate in over 0.2s cubic-bezier(0.4, 0, 0.2, 1) (1 revealed during the drive).
- overlay dropdown (auto-opened): panel rgba(0, 0, 0, 0) · r 0px

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

## Components (measured)
- link: #FFFFFF · no underline

## Responsive (measured)
- breakpoints: 639px · 767px · 1023px · 1279px · 1599px
- mobile (390px): hero 32px · 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.
