A demo of miso's React-style, app-global context feature.
A top-level component seeds the global context and mounts three children. Two of them opt into context updates (mountUseContext) and can mutate it (modifyContext / putContext); the third opts out (mount_) and stays stale. Modifying the context from any context-aware component re-renders all of them together.
Install Nix Flakes, then:
