// Static preload script (not compiled by shadow-cljs). Runs in an isolated
// context with access to Node and the renderer's `window`. Exposes a
// minimal, frozen bridge for the sandboxed renderer to talk to main.
//
// Named `window.noidBridge`, NOT `window.noid`: in the dev (unoptimized)
// renderer build, `window.noid` is the ClojureScript namespace root
// (`noid.graph`, `noid.ui.*`), which the e2e driver reads directly. A
// contextBridge-exposed object is frozen, so it can't also host those
// namespaces without breaking them.
