Timeline Builder

Generate beautiful interactive timeline HTML pages from JSON configuration data, with three layout modes:

1. Vertical layout (vertical) — A classic top-to-bottom timeline with event cards alternating on either side of the axis
2. Horizontal layout (horizontal) — A horizontally scrollable timeline, best for displaying fewer events
3. Dual-side layout (dual-side) — Events are placed on the left or right based on the side field, great for side-by-side comparisons

All layouts support:

• Click to expand/collapse event details
• Mobile-friendly responsive design
• Custom theme colors, icons, and category labels
• Pure static HTML with zero dependencies — opens directly in any browser
