Hey! First of all, thank you for a great platform! I'm interested in how it is implemented. Is there any page that describes the architecture of DB<>Fiddle? The most interested questions for me are as follows: - How and where queries are executed? - Do you use transactions to abort changes and allow arbitrary types of queries? - Is it open-sourced? Couldn't find any repository in GitHub. If no, is it possible to open source it? Thank you in advance.
