# Frontend Env Reference > Generated from `web/env.ts`. Do not edit manually. This reference documents frontend application env semantics and code defaults only. Deploy-time defaults, `.env.example`, Docker files, and runtime-effective values are intentionally excluded. Only env declared in `web/env.ts` is included. Dev-only tooling env outside that file is excluded. ## Browser-Public Variables | Name | Visibility | Type | Default | Injection | Dataset Key | Description | | --- | --- | --- | --- | --- | --- | --- | | `NEXT_PUBLIC_ALLOW_EMBED` | `browser-public` | `boolean` | `false` | `body-dataset` | `allowEmbed` | Default is not allow to embed into iframe to prevent Clickjacking: https://owasp.org/www-community/attacks/Clickjacking | | `NEXT_PUBLIC_ALLOW_INLINE_STYLES` | `browser-public` | `boolean` | `false` | `body-dataset` | `allowInlineStyles` | Allow inline style attributes in Markdown rendering.
