# Andreas Kruszakin Design System

## Overview

Andreas Kruszakin describes itself as: “I'm Andreas, a growth-focused design engineer who is design first and builds the system underneath. I make founders' products easy to get, so customers buy and investors say yes, which so far has meant £1.4M raised for N” The interface is light, built on **White (#FFFFFF)** with **Near Black (#000000)** text, and **Vivid Blue (#00AAFF)** as the main accent.

Type is set in **TRJN DaVinci** and **Geist Variable**. Headlines run large with tight negative tracking; body text is 14px. Depth comes from hairline borders and inset highlights rather than drop shadows. Corners are mostly 10px.

Measured from [andreas.vision](https://andreas.vision/) on November 6, 2026 at 1440×900 and 390×844 from 330 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 10 roles.

- **White (#FFFFFF):** Page background, seen 10 times. Token `background`.
- **Near Black (#000000):** Primary text and headings, seen 36 times. Token `on-surface`.
- **Deep Blue (#2E3342):** Secondary text, seen 6 times. Token `on-surface-variant`, CSS `--button-secondary-background-hover`.
- **Slate (#646465):** Muted text and metadata, seen 16 times. Token `on-surface-muted`.
- **Gray (#9B9B9B):** Subtle text and placeholders, seen 15 times. Token `on-surface-subtle`, CSS `--palette-b40`.
- **Snow (#FBFBFB):** Raised areas one step from the page, seen 10 times. Token `surface-container-low`.
- **Near Black 5% (#0000000D):** Translucent fill for cards and controls, seen 4 times. Token `overlay`.
- **Near Black 3% (#00000008):** Borders and dividers, seen 5 times. Token `outline`, CSS `--tab-hover`.
- **Vivid Blue (#00AAFF):** Brand color on large areas, seen 5 times. Token `primary`, CSS `--link-visited`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.

## Typography

**TRJN DaVinci** and **Geist Variable** share the interface. Fallback stack: `TRJN DaVinci, Newsreader Variable, Georgia, serif`.

- **headline-display:** TRJN DaVinci 132px at weight 400, line height 1.12, tracking -0.04em (50px on mobile). Page title (h1).
- **headline-lg:** Geist Variable 105px at weight 500, line height 0.86, tracking -0.01em (56px on mobile). Section headings (h2).
- **headline-md:** Geist Variable 20px at weight 400, line height 1.45. Sub-section headings.
- **body-md:** Geist Variable 14px at weight 400, line height 1.5. Body text.
- **body-lg:** Geist Variable 16px at weight 400, line height 1.4. Lead paragraphs.
- **body-sm:** Geist Variable 13px at weight 400, line height 1.4. Secondary and small text.
- **caption:** Geist Variable 11px at weight 400, line height 1.5. Captions and fine print.
- **label-md:** Geist Variable 17px at weight 400, line height 1.4. Buttons, navigation and labels.
- **label-sm:** Geist Variable 16px at weight 500, line height 1.4. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 42% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 2.04px, sm 6px, md 16px, lg 20px, xl 48px.
- **Sections:** 120px vertical padding between major sections.
- **Gaps:** 16px is the most common gap in flex and grid layouts.
- **Page margin:** 88px on each side of full-width sections.
- **Breakpoints:** 820px.

## Elevation & Depth

The design avoids drop shadows. Layers are separated by tonal surface steps (#FBFBFB) and hairline rings:

- `rgba(0, 0, 0, 0.03) 0px 0px 0px 1px`

## Shapes

Most elements use 10px corners. Measured radii, most used first:

- **md (10px):** 72 elements.
- **xl (40px):** 60 elements.
- **sm (8px):** 52 elements.
- **lg (12px):** 40 elements.
- **full (9999px):** 36 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-ghost (“How I design”):** transparent fill, #000000 text, 14px/400, padding 0px.
- **card:** #FFFFFF fill, #000000 text, 14px/400, padding 0px.
- **link:** transparent fill, #000000 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #FBFBFB.
- Do keep text in 4 levels: #000000, #2E3342, #646465, #9B9B9B.
- Do use #00AAFF as the brand accent: header, logo and key highlights.
- Do set headlines in TRJN DaVinci with tight tracking (-0.04em).
- Do reuse the measured spacing steps (6px, 16px, 20px).
- Do use 10px corners on most elements; larger surfaces also use 40px, 8px and 12px.
- Don't use #9B9B9B for body text; it reaches 2.78:1 on #FFFFFF. Keep it for large text or metadata.
- Don't add drop shadows for depth; use hairline rings and tonal surfaces.
- Don't introduce new font families beyond TRJN DaVinci and Geist Variable.
- Don't use #00AAFF for large backgrounds or body text.
- Don't make interface transitions slower than 0.6s.

## Motion

Interface transitions are quick: 0.1s, 0.5s, 0.25s, 0.6s. Longer ambient animations run 1.8s.

- **Easing:** `ease-out`, `cubic-bezier(0.16, 1, 0.3, 1)`, `cubic-bezier(0.22, 1, 0.36, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
