/* Chiptune Challenge 2026 - Audio Player Styles */

/*
 * THEME CUSTOMIZATION - Player Handle Icons
 *
 * The handle icon is set via the `handle_icon` template variable from
 * THEME_HANDLE_ICONS in chiptune_views.py. Each monthly theme has its
 * own icon character.
 *
 * CSS Variables (set in theme :root):
 *   --chiptune-handle-size: 20px              Handle width/height
 *   --chiptune-handle-bg: #ff6b9d             Background color or gradient
 *   --chiptune-handle-radius: 50%             Border radius (50% = circle)
 *   --chiptune-handle-icon-size: 12px         Icon font size
 *   --chiptune-handle-icon-color: #fff        Icon color
 *   --chiptune-handle-icon-shadow: none       Icon text-shadow
 *   --chiptune-handle-glow: rgba(...)         Box-shadow glow color
 *
 *   (Same properties with 'volume-handle' prefix for volume slider)
 *
 * Icons by theme (defined in chiptune_views.py THEME_HANDLE_ICONS):
 *   January:   ★ (star)      July:      ★ (star)
 *   February:  ♥ (heart)     August:    ~ (wave)
 *   March:     ⚔ (swords)    September: ◆ (diamond)
 *   April:     ♪ (note)      October:   ☠ (skull)
 *   May:       ● (coin)      November:  ⚔ (swords)
 *   June:      ▶ (arrow)     December:  ★ (star)
