Landmark History GSAP Motion Graphic

You are an expert front-end animator specializing in GSAP (GreenSock Animation Platform) and motion graphics for explainer videos. Your task is to create a visually engaging, timeline-based animation that tells the story of The Sphere in Las Vegas—from its architectural conception to its current status as a premier entertainment venue.

## Animation Brief

Create a 30-60 second GSAP-powered animation with these story beats:

1. **The Beginning** – Minimal architectural wireframe/blueprint of The Sphere emerging
2. **Construction & Completion** – Structure fills in, exterior LED skin activates
3. **Live Music Era** – Major bands and performers take the stage
4. **Cultural Moments** – The Wizard of Oz screening and other landmark events
5. **The Big Reveal** – October 1, 2026: Metallica debuts, with a personal callout: "And guess who's attending? We are!"

## Technical Requirements

- Use **GSAP 3.x** core library; leverage ScrollTrigger or timeline sequencing as appropriate
- Implement smooth easing (Power2, Elastic, or Expo eases) for professional motion feel
- Coordinate text reveals, image transitions, and shape morphs in a single master timeline
- Reference images from: `{{image-folder-path}}`
- Ensure responsive canvas; target 1920×1080 or 1080×1080 for social media
- Export-ready: structure code so it can render to video via a tool like Remotion or canvas-to-MP4 recorder

## Style & Tone

- **Explainer video aesthetic**: clean, modern, high-energy
- Use bold sans-serif typography for dates and captions
- Incorporate neon/LED color palette (electric blues, purples, golds) reflecting The Sphere's exterior
- Add subtle sound-design cues in code comments (e.g., `// whoosh SFX here`) for later audio sync
- Keep it **shareable and viral-ready**: punchy pacing, surprise reveal at the end

## Deliverables

Provide complete, runnable HTML + JavaScript code with:

- Inline GSAP CDN links (or npm import statements if using a build tool)
- Clearly commented timeline structure for each story beat
- CSS for layout and base styles
- Instructions for swapping in actual image assets from `{{image-folder-path}}`
- Brief setup notes (how to run locally, how to record output)

## Context

Make it awesome, make it smooth, and make it something people will want to share.
