         * We... maybe or maybe don't need processes in prelude, since we need to read and write from the boxes; we might be able to do that with closures and functions that call `spawn!` themselves

     - For the above, I've started hammering out a situation. I ought to have followed my instinct here: do a little at a time. I ended up doing all the things in one place all at once.
     - What I've done is work on a bespoke `to_json` method for values; and using serde deserialization to read a string delivered from js. I think this is easier and more straightforward than using `wasm_bindgen`. Or easier; I have no idea what the plumbing looks like.
     - Just to catch myself up, some additional decisions & thoughts:
