Build a leaderboard with Tailwind CSS: rows with rank, avatar, name, score, and a movement indicator (up or down arrow with the number of places, or a dash for unchanged). Highlight the current user's row with a tinted background, medal the top three ranks with a subtle accent, and add a 'your position' sticky row when the list is long. Keep scores right-aligned and tabular.
