# Load one of each from your own site

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Recommended
- Chapter: [Site architecture](https://agentwranglers.se/playbook/website/site-architecture)
- Rule: One HTML request, one inline stylesheet, one script bundle, one image per screen size, self-hosted fonts, and no third-party origins.
- How: Bundle scripts into one module and inline the CSS. Host fonts and images yourself. Set the CSP to `'self'`, plus a hash that allows the inline stylesheet.
- Check: A browser driver records every request on each page type. Every request goes to the page's own origin, with one HTML document, no external stylesheet and at most one script bundle.

Example:

```html
<head>
  <style>/* the whole stylesheet, inlined at build time */</style>
  <script type="module" src="/assets/main-3f9a1c.js"></script>
</head>
```

```http
Content-Security-Policy: default-src 'self'; style-src 'sha256-…'; script-src 'self'; img-src 'self'; font-src 'self'
```
