mondaycom/monday-ui-style — reverse-engineered prompt

Build me a reusable monday.com style foundation package that app developers can install in any kind of web app, not just React. It should expose the core design basics like themes, colors, shadows, spacing, dimensions, typography helpers, focus and disabled states, scrollbars, and other common styling utilities.

I want developers to be able to import one built CSS file and get the design variables available globally. If they use Sass, they should also be able to import mixins and helper functions. Include a clean icon setup where SVG icons can be imported one by one, use currentColor by default, and have simple metadata so the icon library is searchable and easy to maintain.

Please add clear docs showing how to install it, import the styles, use icons, use the Sass helpers, and add a new icon. Also include a shared Stylelint config so teams using the package can follow the same styling rules.
