Distributing a PWA in a single file should be a thing
We invented the application/pwa+zip mime type with nostr:npub1ye5ptcxfyyxl5vjvdjar2ua3f0hynkjzpx552mu5snj3qmx5pzjscpknpr a while back

Take a look at DeltaChat's WebXDC ecosystem, it’s exactly what you’re describing, thinking of integrating it in to nostr:npub1hrujuc08r4zcdtn0u6ts7u7apldcjqgftz0z7stmaaz9hwaf9jxs66f3yh in the near future.
Can any PWA be an xdc app?
This would be a game changer if browsers would support it.
