Remote Ocean Point Data Animation

You are an expert data visualization developer specializing in geospatial storytelling and interactive cartography. Build a complete, production-ready web-based data animation that reveals the profound isolation of Point Nemo—Earth's most remote oceanic point—and its role as humanity's spacecraft cemetery.

## Animation Requirements

### Scene 1: Geographic Isolation (0-15s)
- Render an interactive globe centered on Point Nemo (48°52.6′S 123°23.6′W) in the South Pacific
- Animate three expanding radius circles showing nearest landmasses:
  - Ducie Island (Pitcairn): 2,688 km north
  - Motu Nui (Easter Island): 2,515 km northeast  
  - Maher Island (Antarctica): 2,515 km south
- Label and pulse these land points; display distance metrics in both kilometers and nautical miles
- Use ocean bathymetry data to show seafloor depth (~4,000m) with gradient shading

### Scene 2: Vertical Perspective (15-30s)
- Split-screen comparison showing:
  - **Left**: Cross-section from Point Nemo to nearest land (horizontal distance)
  - **Right**: Vertical line from Point Nemo to ISS orbital path (408 km altitude)
- Animate a silhouette of the ISS passing overhead with orbital trace
- Display bold comparison text: "Astronauts overhead are closer than any human on land"
- Scale both distances proportionally with a shared ruler

### Scene 3: Spacecraft Graveyard (30-50s)
- Overlay animated trajectories of deorbited spacecraft (1971-present) converging on the region
- Visualize ~263 spacecraft as descending arcs, color-coded by origin:
  - Russian/Soviet (Mir, Progress, Salyut): red
  - American (Skylab components, cargo): blue  
  - European/Japanese/Commercial: green
- Highlight Mir space station (2001) with callout and mass (120 tons)
- Show accumulation heatmap on ocean floor; label the cemetery zone (~1,500 km radius)
- Display running counter of total mass deposited

### Scene 4: Context & Scale (50-60s)
- Pull back to full Earth view showing Point Nemo's position relative to major cities
- Overlay flight paths from {{reference-location}} to illustrate comparative remoteness
- Final stat card: surface area of the exclusion zone vs. land comparisons (larger than Alaska)

## Technical Specifications

**Stack**: {{tech-stack}}

**Data Sources** (use or simulate):
- Coordinates: WGS84 datum
- Bathymetry: GEBCO or ETOPO datasets
- Spacecraft registry: publicly available deorbit records (NASA, Roscosmos)
- ISS TLE data for orbital visualization

**Visual Standards**:
- Smooth 60fps animations with easing functions (ease-in-out-cubic)
- Dark theme optimized for ocean depth (deep blue #001a33 base)
- Accessible color palette (WCAG AA contrast)
- Responsive design (mobile portrait through 4K landscape)
- On-screen legends, scale bars, and coordinate grid
- Subtle ambient audio cues (optional): water, orbital hum

**Interactivity**:
- Pause/play/scrub timeline controls
- Click spacecraft for metadata (name, date, mass, origin)
- Toggle layers (bathymetry, trajectories, distances)
- Export current frame as PNG

## Deliverables

Provide:
1. Complete source code with clear file structure and comments
2. Package.json / dependencies manifest
3. README with setup instructions and data attribution
4. Inline comments explaining coordinate transforms, projection choices, and animation timing
5. Fallback static visualization for unsupported browsers

Emphasize the haunting scale: the loneliest place on Earth is where we retire our spacecraft—a monument to human reach, located beyond human touch.
