404 - This host is not configured

Custom 404 error page for KajKowalski Edge.

A storm-themed page that displays "404 - This host is not configured" when a visitor reaches an unconfigured hostname.
The page dynamically inserts the current hostname, features animated lightning bolts over a dark atmospheric background, and automatically activates a calm mode for users who prefer reduced motion.
