Block Forge

An article builder for React, with Editor.js underneath and shadcn/ui on top. Its interface is made of shadcn/ui components on Tailwind CSS, and even Editor.js's own toolbar and popovers take their colours from shadcn/ui's tokens.

It runs as a full page, a centred sheet with its own menubar, or embedded in a form, where it fills its container and takes the host's font. The theme is light, dark or the system's, and the block tools come in presets that load on demand.
