Show HN: I added stacked subgraphs to Mermaid flowcharts

I’m an avid user of mermaid but am constantly annoyed by their limitation that subgraphs do not follow direction if any internal nodes are connected to the outside. So I asked Claude to add a new syntax called stack layout and it seems to work pretty elegantly.I also fixed my annoyance with mermaid.live and allowed this playground to save snapshots in your local storage as well. Happy to add more storage features if anyone’s interested!The one prompt fork is at https://github.com/ramraj07/ra-mermaid
