Deno workspaces and Fresh, a viable combination?

Hello! I'm attempting to port an existing project to Deno and Fresh. I'm still working on the initial setup, and I have a structure like this:
/
├── deno.json
├── server/
│     ├── deno.json
│     └── a Fresh installation
└── lib/
      ├── deno.json
      └── old code to be ported

I want to separate the code to port and the Fresh installation as one will be ripped apart and the other should already be functional, and figured I could use workspace to join everything up, but I'm struggling to get it to work.

First off, the workspace for lib cannot have a name, as there is not one file but a range of files to reference. Do I need to create an index.ts file in there to reference to make this work at all? I already have a generator for that so should be possible but it'll be a large one. I want this so I can reference the stuff in there without the eventual ../../../lib/###.

If I remove the name from the subfolder deno.json, the error for missing a file goes away, but instead I get this error from the Fresh installation: 
error: Relative import path "preact" not prefixed with / or ./ or ../ and not in import map from "https://esm.sh/v135/preact-render-to-string@6.3.1/X-ZS8q/denonext/preact-render-to-string.mjs"
    at https://esm.sh/v135/preact-render-to-string@6.3.1/X-ZS8q/denonext/preact-render-to-string.mjs:2:46

Is using workspaces with Fresh even a reasonable approach at this point in time, or should I try to move the Fresh deno.json to my root folder and run it all from there? I mostly want it there so scripts can be executed from the root of the project, but maybe that is just wishful thinking.

Thinking about it now it feels like I should just leave the deno.json in the ./server folder, hopefully the compile settings will still apply to the other folders for the language server even if they are a level outside.

There's many things I'm unsure of here, but figured I could leave a post here with my musings, I'll be back tomorrow 😅 This is so I can sleep after having spent many hours trying to make sense of Fresh today, sadly I'm not that fresh myself so it's been slow going!
