flowmanceLeo Lutz Design System
Leo Lutz is a quiet, dark one-person resume. It feels like a gallery wall at night: a pure black page, very light Satoshi set large and calm, and one colourful portrait that stays pinned on the left while everything else scrolls past on the right. There are almost no boxes. Structure comes from hairline rules, alpha-stepped white text and space.
Four signatures make it recognisable:
- The pinned, tilted portrait. The left half of the page holds one portrait photo, skewed in perspective (the near edge taller than the far edge), sticky for the whole page, and nudged by the mouse. The right half carries the content.
- Light-weight poster type. Headlines are Satoshi 300: the hero Digital Designer Based In London. at 8vw (115px at 1440), section titles at 43px, and metrics at 100px.
- Rolling counters. Metrics (394+, 79, 300%) are built from digit columns that roll upward on load, with a smaller grey affix (+, %) beside them.
- The ©-name logo and round controls. The logo reads ©Leo Lutz top-left; the menu is a hamburger inside a thin 1px circle top-right; a small light/dark switch sits bottom-left.

Do’s and don’ts
- Keep the canvas pure #000000 and text pure #FFFFFF, stepped down only by alpha (60% for body, 70% for meta).
- Set every headline in Satoshi 300: 115px hero, 43px sections, 100px metrics.
- Pin one portrait on the left and scroll all content in the right column.
- Separate items with 1px white-20% rules instead of cards or panels.
- Use #1B1B1B square buttons (3px radius) that invert to white on hover.
- Keep project photography black and white.
- Add an accent colour, gradients on UI or drop shadows.
- Use Playfair Display or any serif, even though the page loads it.
- Set headlines in bold or uppercase; capitalised Title Case is the most emphasis the hero gets.
- Use ink-faint (36%) below 20px or for anything a reader must read; keep it for menu group headings.
- Round images or put content in filled cards.
- Animate longer than 500ms, except the 2500ms counter roll.

Claude, ChatGPT, Gemini, Cursor and v0, or any other AI tool that builds pages or code.
How to use it
- Put
DESIGN.mdin your project and mention it in your request, or save it as.cursor/rules/leo.mdc - For the rule file, start it with a front-matter block that sets
alwaysApply: true, so every chat uses it - Ask: “Build a pricing page using DESIGN.md.” Cursor follows the colors, fonts, spacing and rules
- Put
DESIGN.mdin the project root - Add one line to
CLAUDE.md: “Follow DESIGN.md for all UI.” - Ask for any page or component; Claude reads the file first
- Attach
DESIGN.mdto the chat (or paste it in) - Ask: “Build a landing page in this design system.”
- Keep the file in the chat or project knowledge, so follow-up pages stay on style
What it is

Best for
Figma (Tokens Studio), Style Dictionary and other design-token tools, and build scripts.
How to use it
- In Figma, open Tokens Studio, choose Import, and pick
tokens.json - Or point Style Dictionary’s

What it is
A Tailwind CSS v4 theme: every color, font, type style, radius and spacing value becomes a Tailwind utility, like bg-canvas, text-headline-lg or rounded-md.

- Add it to your stylesheet, or in Webflow paste it into Site settings → Custom code inside a
<style>tag - Use the variables anywhere:
