Read the whole file to bytes so we can transparently skip an optional UTF-8 BOM (EF BB BF). serde_json does not strip a BOM and would otherwise fail the parse with "expected value at line 1 column 1" for any file produced by editors / tools that default to BOM-prefixed UTF-8 (e.g. Windows PowerShell 5.1's
Set-Content -Encoding UTF8, Notepad, VS Code's "UTF-8 with BOM").
