Currently the table delimits pricing in "$" and there is a note below the table that All storage and retrieval charges are denominated in USDFC (or supported ERC-20 tokens) and settled via Filecoin Pay. - The current state of things looks good to me, but welcome any alternatives or changes from anyone? I would ignore this nit because accepting it makes the denomination of funds inconsistent within the table

Thanks @snissn; I'm going to convert this to draft for now until we actually have this implemented anywhere. Language and code design for the SDK is going on in #763. There's some things to iron out in here like the proving service fee should be 0.0024; the floor price needs to be removed from above this edit; we need to harmonise on name ("Network Congestion Fee" instead of Sybil is I think what we're going to go with); there's a lockup for lifecycle operations. See FilOzone/filecoin-services#469 for more detail on the contract side, still to be implemented though.
We'll probably also want to harmonise a little on the split of 3 titles: "rates", "fees" and "lockup" so we can explain these things a bit more clearly because it gets confusing very quickly. As a headline we can probably make "lockup" fade into the background as an implementation detial but it's going to need to be properly covered somewhere.

@snissn : are you to pick this up to get this PR ready for review given all the pricing changes are in FWSS and being deployed and we have the Synapse SDK changes staged?
