<#
  setup.ps1 - one-shot installer for the Eve Retriever ore-hold watcher.
  Run from an ADMIN PowerShell. Installs Python + Tesseract (via winget),
  installs python deps, creates config.ini with a fresh random ntfy topic,
  and offers to fire a test alert.

  You normally don't call this directly - use the one-liner in the chat /
  README, which pulls the repo first and then runs this.
