The ?i= redirect is gone, so only bare queries are promoted, and the rewrite encodes + as %2B so static files no longer redirect to their encoded name. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

// Sets the zone's URL Rewrite Rules that turn a bare query into its site's static file path (/orange+cat →
