StackImages web pages: a copy to put on your own web site
=========================================================

1. Upload this whole StackImages folder to any directory of your web site, unchanged.
   The home page is StackImages/index.html; Show Clusters is StackImages/ShowClusters/
   and HR Diagram of Your Own Image is StackImages/HRDiagram/.
   Nothing to install or run on the server: these are ordinary static files.

2. Open it through the web server (https://...), not from your disk (file:///...):
   browsers do not run the page's background worker from local files.

3. No server settings are needed. The page works whatever content types the server
   sends for its .wasm, .whl, .npy and data files (application/octet-stream is fine),
   as long as .js, .html and .css have their usual types.

Show Clusters reads star data from GAVO (https://dc.g-vo.org) in the visitor's browser,
so a Content-Security-Policy must allow connect-src https://dc.g-vo.org (https: covers it).
Both pages show diagrams as data: images, so it must also allow img-src data:.
