The byproduct of Plavna's development is a small design system that embodied the values I've loved in design for years: animation — elements respond to hover with a soft glow and parallax, popups "inflate" on opening, checkmarks appear as if drawn with a pen, etc; customisation not only for colors and corners, but spacings, fonts, and shadows — all encompassed into Swiss minimalism on a tidy modular grid.
The design system is written for Svelte 5. Right now you can use it as a reader or an author in this app. I can also open source it if enough people show interest.
