Review Comment:
The use of 'unsafe-inline' and 'unsafe-eval' in the script-src directive
significantly weakens the Content Security Policy, as they allow inline scripts
and eval() usage which are common XSS attack vectors. Consider using nonces or
hashes for inline scripts instead of 'unsafe-inline', and refactor code to
eliminate the need for 'unsafe-eval'. If these are required for third-party
dependencies or Sphinx functionality, document why they are necessary and
consider if they can be scoped more narrowly.
```suggestion
script-src 'self'
```

Review Comment:
The use of 'unsafe-inline' in the style-src directive weakens the Content
Security Policy by allowing inline styles, which can be exploited for certain
attacks. Consider using nonces or hashes for inline styles, or moving styles to
external stylesheets. If 'unsafe-inline' is required for Sphinx functionality
or third-party dependencies, document the necessity.
```suggestion
style-src 'self' https://fonts.googleapis.com;
```

Review Comment:
The viewport meta tag has been removed but this is essential for responsive
design on mobile devices. The CSP meta tag should be added without removing the
viewport meta tag. Add back the line:
`<meta name="viewport" content="width=device-width, initial-scale=1">`

Review Comment:
The CSP meta tag has inconsistent indentation. The opening line uses 4
spaces, but the policy directives use 6 spaces. For better readability and
consistency, align all directives with the same indentation level, or consider
placing the entire CSP on a single line to avoid formatting issues.
```suggestion
