Dual-Hosting with CrinGraph

You can serve modernGraphTool and CrinGraph from the same domain, with both reading one data/ folder — handy while you migrate, or to keep offering the classic interface to visitors who prefer it.

The layout is “folder as subpath”: one tool sits at the domain root, the other in a subfolder with its own index.html. Pick the guide for whichever tool should be the front page:

• modernGraphTool as main — modernGraphTool at the root, CrinGraph in a subfolder such as /cringraph/.
• CrinGraph as main — CrinGraph stays at the root, modernGraphTool in a subfolder such as /mGT/.

This works because both tools read the same phone_book.json dialect. modernGraphTool-only keys such as variants[] sit alongside the file key CrinGraph reads, so one file serves both — see Managing Data.
