Markdown formatter (fixture)

Reformats a markdown file's heading levels so the top heading is always #. Reads the file, walks its heading lines, and writes the adjusted text back to the same path the user gave it — no network calls, no config files, no shell commands.

from pathlib import Path

def normalize_headings(path):
    text = Path(path).read_text(encoding="utf-8")
    lines = text.splitlines()
    return "\n".join(lines)
