## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
_GitHub: created 2026-03-07 · updated 2026-03-07 · closed 2026-03-07_
Sobelow reports missing CSP on the browser pipeline (`router.ex:14`). Add a basic CSP via `put_secure_browser_headers/2`.
Currently the app does not set a `Content-Security-Policy` header, which is a defense-in-depth measure against XSS and other injection attacks.
