/*
 * LEADERBOARD TABLE - Flex-based layout for consistent display
 *
 * RESPONSIVE DESIGN: Table fits its content and centers in the container.
 * No percentage-based widths - columns size based on content + padding.
 *
 * NO INTERNAL SCROLLING: Table displays all content naturally without
 * internal scroll mechanisms. Users scroll the entire page instead.
 * This ensures consistent behavior across all zoom levels.
 *
 * Layout: Flex-based structure where:
 * - Table width is auto (fits content), centered with margin: 0 auto
 * - Rows use flex for column alignment
 * - Columns use auto width with padding for spacing
 * - 3-column layout: Rank, Possible ID, Level

 * Only .leaderboard-page.active should be visible.
