create a minimal version, with base principles
- encode/decode to/from URL
- one element with
contenteditable - qr-code
- print styles
- markdown → HTML support?
- correct title
- minimal interface (maybe just url param, no subdomain, too much to deploy)
- no rtc, no yjs → as a "plugin system"?
- drop build tool, use @sctlib/emacs-ssg for dev deps build example page & static site?
maybe there are actually too much "important features" to drop the build tool, and go without dependencies
