curl -I https://your-domain.com/llms.txt

// 1. Place the file at: public/llms.txt

# WordPress, three options
#
# 1. Easiest: upload llms.txt to your hosting (FTP/SFTP) at the web root.
#    Verify: https://yoursite.com/llms.txt
#
# 2. Plugin: any "static file uploader" plugin works. Place file at root.
#
# 3. Programmatic: add a small handler to your theme's functions.php
#    that intercepts the request and returns the file contents.
