stroblmeandClaude Opus 5.5 6c0ab2049b Send a CSP and security headers from the frontend's nginx
script-src admits the bundle and the pre-paint theme script by hash, with no
unsafe-inline or unsafe-eval; style-src keeps unsafe-inline for the <style>
elements Monaco, Radix and the toasts insert. frame-ancestors 'self',
nosniff and strict-origin-when-cross-origin go with it, and the Dockerfile
adds the API origin to connect-src when the bundle calls one elsewhere. Zod
runs jitless so its eval probe is not reported on every page. The embed
widget keeps allow-same-origin: the demo's weather map does not render
without it; the comment now says so and what it costs.
