@mrudulpatil18 is attempting to deploy a commit to the tscircuit Team on Vercel.

A member of the Team first needs to authorize it.

This is excellent, can you add a playwright test that shows that it works (and prevents others from breaking it?)

Ah ok- so there's a bit of an issue. You should not have to run the code in the iframe, we should be loading circuit json that is precompiled. I believe snippet.circuit_json can be used to get precompiled circuit json code (if not, we will want to introduce snippet.circuit_json)

Basically if someone wants to embed a circuit on their website, their users shouldn't have to hit run.

@seveibar can you please take a look at the changes. Lots of changes through this PR:

• now uses snippet.circuit_json for /preview route
• can add &view parameter to url with values "pcb", "3d" and "schematic"
• defaults to pcb view if not mentioned
• added circuit_json in seed.js to allow fake-snippets db tests

Nice work
