Census — Design System

light · professional · medium · custom · confidence 92% · deep decode

Census keeps data activation matter-of-fact: Inter at 44px/700 in near-black #222222 on white, 16px body, cobalt #306BEA buttons at a sharp 4px radius. Pipeline diagrams and warehouse logos carry the argument without a single decorative flourish — the design system of a company betting that in data infrastructure, plain speech is the premium look.

# Census — Design System

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

Census keeps data activation matter-of-fact: Inter at 44px/700 in near-black #222222 on white, 16px body, cobalt #306BEA buttons at a sharp 4px radius. Pipeline diagrams and warehouse logos carry the argument without a single decorative flourish — the design system of a company betting that in data infrastructure, plain speech is the premium look.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DDDDDD` |
| text | `#222222` |
| text_muted | `#757575` |
| primary | `#306BEA` |
| accent | `#306BEA` |
| link | `#8CB1FF` |
| secondary | `#001525` |
| button_bg | `#306BEA` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#306BEA` — 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 `#306BEA` — one role, not several (your action color).
- **accent** `#306BEA` — 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** `#8CB1FF` — fails contrast on the background (~2.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#001525` — 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` 66.5% · `#081623` 10.2% · `#396BD9` 6.4% · `#A49F9E` 5.9%

## Typography

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

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 44px / 700 · lh 52px · tracking 0.16px |
| h2 | 36px / 700 · lh 44px · tracking 0.16px |
| h3 | 28px / 700 · lh 36px · tracking -0.19px |
| body | 16px / 600 · lh 24px · tracking -0.19px |
| small | 14px / 500 · lh 20px · tracking 1px |
| eyebrow | 14px / 500 · tracking 1px |

- Weight ladder: 400 · 500 · 600 · 700 — 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: 2px, 7px, 8px, 10px, 11px, 12px, 16px, 20px, 21px, 24px — snap all gaps/padding to these

## Radius
- base: 4px
- button: 4px
- card: 4px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#306BEA` / `#FFFFFF` | 1px solid rgb(48, 107, 234) | 4px | 8px 16px 8px 16px | 600 16px / -0.19px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#222222` | 1px solid rgba(0, 0, 0, 0) | 4px | 7px 7px 7px 7px | 600 14px / -0.19px | none |

**States (measured, not guessed)**

- primary hover: border `1px solid rgb(46, 84, 182)` · background `#2E54B6`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: border `1px solid rgb(198, 221, 255)` · background `#C6DDFF`
- transition: `all 0.2s ease`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 0px 18px 0px`

## Motion
- durations: 200ms (dominant) · 100ms · 500ms
- easings: `ease` (dominant) · `linear`
- animated properties: color, opacity, transform, 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.

## 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.
