| // Dev-only diagnostics entry. Statically imported from `main.tsx` ABOVE the | |
| // `react-dom` import — that ordering is load-bearing and non-negotiable. | |
| // | |
| // react-dom captures the devtools hook at MODULE INIT, not at `createRoot`. | |
| // Verified: installing bippy after react-dom has evaluated yields | |
| // `renderers=0` and `commits=0` — the hook object exists but react-dom never | |
| // registered with it. A dynamic `import()` here would resolve a microtask | |
| // after main.tsx's static graph (react-dom included) had already evaluated, | |
| // so it must be a plain static import chain, whose evaluation order ESM | |
| // guarantees. | |
| // | |
| // Production builds don't tree-shake this away (a static side-effect import | |
| // can't be eliminated) — instead `vite.config.ts` aliases this module to | |
| // `dev-only.noop.ts` whenever the build isn't serving dev, so neither bippy | |
| // nor the counters reach a shipped renderer. | |
