+"""Gradio frontend for the MLE‑Dojo leaderboard.
+
+Changes made in this version
+----------------------------
+1. **Fixed CSS syntax errors** (missing semicolons, misplaced `!important`).
+2. **Introduced a single, clean rule‑set** for the introduction block so the
+   font size, family and alignment are now reliably applied.
+3. All new comments are in English for clarity.
