/* ============================================
   BLITZEN2D RETRO THEME (DARK MODE)
   Fomantic UI Overrides for pixel-art aesthetic
   ============================================

   THEME PARITY INSTRUCTIONS
   -------------------------
   This theme file must stay in sync with its counterpart:
   - Dark: theme-retro.css (this file)
   - Light: theme-retro-light.css

   When adding new CSS variables or classes:
   1. Add to BOTH theme files
   2. Only change color values, keep structure identical
   3. Test both themes after any changes

   HOW TO USE THEME VARIABLES
   --------------------------
   Always use CSS variables for colors so themes work:

   GOOD: background: var(--retro-bg-dark);
   BAD:  background: #1a1a2e;

   Available variables:
   --retro-bg-dark      : Main background
   --retro-bg-medium    : Card/segment backgrounds
   --retro-bg-light     : Hover states, highlights
   --retro-primary      : Accent color (buttons, links)
   --retro-secondary    : Secondary accent
   --retro-success      : Success states (green)
   --retro-warning      : Warning states (yellow)
   --retro-error        : Error states (red)
   --retro-info         : Info states (blue)
   --retro-text-primary : Main text color
   --retro-text-secondary: Subtle text
   --retro-text-muted   : Disabled/hint text
   --retro-border       : Borders, dividers
   --retro-border-light : Lighter borders
   --retro-glow         : Glow effect color
