Ah, already escaped webdev hell, I see.
Today I am releasing "noflux", a lightweight RSS and Nostr longform reader for the desktop and personal servers: https://github.com/fiatjaf/noflux
It supports all sorts of RSS feed discovery from HTTP URLs and renders them beautifully in a simple straightforward interface, you can also paste nostr:... URIs, including nip05, npub and nprofile codes (they should also work without the nostr: prefix).

You coulda gone full-native, and escaped the Horror House of Browsers, but I guess this is your compromise.
