For agents
Fetch four files. Build on brand.
Everything an agent needs to build a screen, a page, or an email in this system, with versions and a checksum so it can prove what it built against.
The files
01
tokens.json
Every color role, type role, radius, spacing, and motion value. Light and dark. DTCG 2025.10.
02
tokens.css
The same values as CSS custom properties. Paste into any project and use the roles, never a hex.
03
components.json
Every primitive with its class, markup shape, contract, and the tokens it consumes.
04
llms.txt
The index an agent reads first: files, pages, rules, and the paste-ready prompt block.
Prompt block
Paste this into any agent.
Use the Luckiest Man Ventures brand system at https://brand.luckiestmanventures.com. Pull /system/tokens.css and /system/components.json before writing any UI. Fonts: Fraunces (display), Source Serif 4 (reading), Inter (controls), JetBrains Mono (ids and code). Identity colors: navy #123260, rust #c24c32. Every boxed element contrasts its section. Control heights 32, 40, 48. Fields reserve label and help slots. No pills. No em dashes.
Rules an agent must follow
Contracts, not suggestions.
- 01Luckiest Man Ventures is the umbrella. lightbreak is one product in the portfolio and is always lowercase.
- 02Warm palette only. Warm-white is #fffaf0, never #ffffff.
- 03Every boxed element sits darker than the page it is on. No white or warm-white cards on cream.
- 04Low radius only, 2 to 8px. No pills or fully rounded wide shapes.
- 05Identity colors are accents on marketing pages and appear only in actions, active states, and marks on product pages.
- 06Do not use em dashes.
- 601Use semantic roles from tokens.css, never a raw hex.
- 602Contrast is measured at build time. Do not introduce a pair that is not in the report.
