// 6. Cover root WITH colon (To cover line 413 in image_9e987d.png)

// 7. Cover path WITHOUT any colon (To cover line 490 in image_9e9859.png)
assert.strictEqual(path.win32.normalize('CON'), 'CON');

// 8. Cover path WITH colon but NOT reserved (To cover partial branch at 490)
assert.strictEqual(path.win32.normalize('C:file.txt'), 'C:file.txt');

// 9. Ensure reserved names with colons get the .\ prefix (To fully green line 490)
