A multi-layered script-based artifact is provided, originating from a legacy Windows HTML application format. At first glance, the content appears heavily obfuscated and padded with encoded and non-printable characters, hiding its true execution flow across multiple scripting layers.

Your task is to analyze and progressively deobfuscate the file to understand how it constructs and executes its final payload. The challenge focuses on tracing nested encoding stages, cleaning structured noise, and following the script’s execution path until the underlying network behavior and infrastructure become clear.
