Sitemap/robots.txt, custom 404, redirects, per-page SEO, and CSP — deployment questions

[tblackmon-create]

Hi team — really enjoying working with Instatic so far. A few questions as we get close to launching a client site, some of which might be missing features and one might be a bug:

1. Sitemap.xml / robots.txt — Both return 404 on our deployment. Is there a way to have these auto-generated, or a place to supply static files at the domain root?

2. Custom 404 page — Unknown URLs return a bare JSON body ({"error":"Not found"}) instead of an HTML page. Is there a setting for a custom 404, or is this on the roadmap?

3. Server-level redirects — We're migrating an old site with a couple hundred URLs that need to map to new ones. We checked Data, Settings, and Plugins in the admin and did not find a redirects feature. Is this possible at the hosting layer (e.g. on Railway), or planned?

4. Per-page/per-post SEO fields do not appear to affect output — This might be a bug: individual Posts have seoTitle/seoDescription fields in the editor, and we have filled them in, but every page on the published site (including individual post pages) renders the identical site-wide default <title>/meta description instead. Is there a step we're missing to wire these up, or is this not yet implemented?

5. CSP and third-party scripts — The default script-src 'self' policy blocks things like Google Analytics. Is there a supported way to allow-list specific third-party scripts per-project?

Any pointers appreciated — trying to figure out what's possible before our launch date, and what we should plan to build around instead. Thanks for the great tool!
