 * Additional styling for the leaderboard page
 *
 * The global header and XP bar elements inherit colours from the base
 * stylesheet. On the leaderboard page these values appeared too dark
 * against the background, making text like the site name (HexaGameHub),
 * level indicator (Lv • XP) and the “Leaderboards” heading difficult to
 * read. The rules below override those colours to brighter hues in
 * keeping with the neon arcade vibe.
 *
 * We also remove the deprecated local‑scores notice and give the
 * “Return to Game” button a distinctive gradient so it stands out.

 * against the dark background. These rules give them the same neon
 * gradient as the return button and ensure they adapt gracefully on
