I made this concept blog. Single static page, all cdn JS imports. I’d change the blog page identifier to include a target relay/s (with pubkey + 30k kind). It loads from profile/meta for sidebar content. Supports markdown.

Easy enough to add an editor using window.nostr. You’d still want to trust the static file host perhaps.

Is this the direction you’re thinking?
