## Design Techniques

- Planetary sphere as main scene actor
- Orbital ring line decoration for cosmic context
- Star decorations (star5 preset) with varying sizes and opacity
- Extensive ghost mechanism (25+ actors pre-defined on slide 1)
- Space-themed color progression across slides
- 7-slide narrative structure for comprehensive storytelling
