/**
 * Radostna Leaderboard Stylesheet
 *
 * Styles the influencer leaderboard tables rendered by the
 * [radostna_top300] and [radostna_top100ugc] WordPress shortcodes.
 *
 * Naming convention (BEM-influenced):
 *   .radostna-leaderboard-*   — Base block styles, always present.
 *   .radostna-top300-*        — Leaderboard type identifier class (no extra rules by default).
 *   .radostna-top100ugc-*     — Leaderboard type identifier class (no extra rules by default).
 *
 * Every container always carries both the base `.radostna-leaderboard-*` class
 * and a type-specific class, so the base selectors are sufficient for all shared
 * styles. Type-specific selectors are reserved at the bottom of this file for
 * future per-leaderboard overrides.
