Building the Index

To generate wizsearch.html and wizindex.json for this collection:

1. Download wiz.zip from the WizSearch bundle
2. Drop it into any LLM chat with access to this folder
3. Point the LLM at the letters/ folder
4. The LLM will scan all .md files, build the index, and output the two WizSearch files

Once built and pushed, the live search page will be available at: https://g0rd33v.github.io/wizrag/wizsearch/demo2/wizsearch.html
