/*
 * ============================================================================
 * TIMELINE OVERLAY COMPONENT v1.0
 * ============================================================================
 * 
 * PURPOSE:
 *   Provides all styling for the inline timeline within the Casefile overlay.
 *   Used by slice system and main game for displaying timeline events.
 *
 * STRUCTURE (DO NOT MODIFY):
 *   - DOM nesting (.eg-timelineInline > .tl-viewport > .tl-canvas > markers)
 *   - Grid layout for event cards (1fr 340px)
 *   - Marker positioning (absolute within canvas)
 *
 * SAFE TO CUSTOMIZE:
 *   - Colors (gold accent: rgba(214, 170, 95, ...))
 *   - Spacing (padding, margins, gaps)
 *   - Font sizes
 *   - Shadows and borders
 *   - Animation timing
 *   - Hover effects
 *
 * TO MODIFY INTENTIONALLY:
 *   1. Make your changes in this file
 *   2. Test with multiple slices
 *   3. Document what you changed and why
 *
