Description
Something like, but not quite:
plug :put_secure_browser_headers, %{"content-security-policy" => "default-src 'self'"}
ToDo:
- Add a sensible CSP to the router
- Remove the exception for this rule from sobelow and
Notes:
First attempt: https://github.com/nccgroup/sobelow/issues/61#issuecomment-610660542
Stu says: "The issue with this policy is that all inline styles, svgs etc are blocked. This also includes any DOM changes that LiveView sends that do things inline styles like display: none; also don't work."

Research direction
Start in router.ex and review the existing Sobelow exception for this rule. Compare the proposed CSP with the notes about inline styles, SVGs, and LiveView DOM updates, then verify the policy with the relevant Sobelow checks. Done means a sensible router CSP is in place and the exception is removed without breaking the noted LiveView behavior.
