-- All `.ps1` files **must** be saved with UTF-8 BOM encoding. PowerShell 5.1 defaults to Windows-1252, which corrupts non-ASCII characters (checkmarks, box-drawing) and causes parse errors.
+- All `.ps1` files **must** be saved with UTF-8 BOM (`EF BB BF`). PowerShell 5.1 defaults to Windows-1252, which misinterprets multi-byte UTF-8 sequences (e.g. `✓`, `╔`) as string delimiters, causing parse errors. **Some edit tools strip BOM on save** -- run `.\fix-bom.ps1` (gitignored dev utility) to re-apply after editing.
