GitHuby Card Studio — Ultimate UI v2

This version keeps the original repository managers and asset manifests while replacing the crowded single-page layout with a structured studio interface.

Upload / replace

Replace:

• index.html
• css/style.css
• js/app.js

Keep the existing repository folders and manager files:

• js/config.js
• js/themeManager.js
• js/fontManager.js
• js/languageManager.js
• js/templateManager.js
• js/backgroundManager.js
• js/mapManager.js
• js/cardManager.js
• js/exportManager.js
• assets/**

The existing repo contains 36 themes in assets/themes/manifest.json and 6 original templates in assets/templates/manifest.json; this UI renders those dynamically and adds an additional system/UI template library on top.
