**What should the file have been detected as? What has the file been misdetected as?**
I have tried to input the .env file with edge case content

```
text=""
value="1234"
body="

kokot

it got classified as HTML.

It should be .env, but it is clearly and edge case.

**Please link or attach the misdetected file below** (Do NOT upload PII!)
File included up.

**Additional context**
None

Start by reproducing the detection result with the attached .env sample and compare it with the reported HTML classification. Trace the file-type detection path to determine where this edge case is handled. Done means the sample is classified as .env rather than HTML, with the behavior verified against the attached input.
