Read a trace
Paste the document from GET /__emulator__/trace. It renders here, in this
tab. Nothing is uploaded — there is no server to send it to and no
request is made. Traces carry your record field values, which is also why the emulator
keeps them in memory and never writes them to disk.
The same renderer draws the panel inside the playground and the still on the home page — one implementation, so a document cannot be shown three different ways. What the trace contains.
