## Accuracy constraints (do not invent)

- Do not document Dynamic Labs as a working Auth Modal adapter.
- Do not claim `showPoweredBy` / custom powered-by URL / `theme.title` override the Web5 Nexus footer.
- Only Web3Auth enables Bitcoin key export / `@web5nexus/authmodal-bitcoin`.
- Prefer current package versions from npm / monorepo `package.json` over guessed versions.
