Minor CSS issue on the 'pangram' tile

Just noticed on Chromium v144 (via Vivaldi), when you have found the pangram word of the puzzle and hover its tile, the tile is cut off at the top, see: <img width="178" height="94" alt="Image" src="https://github.com/user-attachments/assets/b636b2ed-79c9-462e-ac39-e555c6fb6a5e" /> Reason seems to be the `--un-translate-y: -1px;` that gets added on hover.
