What is in the download

• A standalone Vite + React + TypeScript + Tailwind CSS project: src/tool holds the tool, shared pieces sit beside it
• package.json with exact versions plus a lockfile, so npm ci works
• README.md (run, build, embed in Next.js or plain React) and an MIT LICENSE

What the code does

• Three layouts described as plain drawing ops in millimetres
• One op list drives both the SVG preview and the jsPDF output
• Bleed extension and crop marks for single cards
• Edge-to-edge sheets with cut marks and a duplex-mirrored back

Tech stack

React 19, TypeScript, Vite, Tailwind CSS 4, jspdf.

Install and customise

The How to install and How to use tabs list the steps. In short: unzip, npm ci, npm run dev, then copy the tool folder into your own app if you want to embed it.

Good to know

• A browser-only tool: there is no backend or database in the code.
• Latin text only in the PDF; colours are RGB, not CMYK.
