For a single-value Workflow 9.2 token, is there a size limit in terms of how much data it can hold? For example, will a token only store a certain amount of data (in bytes) or characters before it stops accepting more data?

I have not hit any such limits so far, but I plan to build a workflow that will potentially store a lot of data in a single token (per workflow instance), so I wanted to ask upfront.

Thanks!
