+## Design Techniques
+
+- **Grain noise texture**: Scattered small ellipses at low opacity (0.02-0.03) for analog feel
+- **Sparkle cross element**: 4-line cross shape (0.08cm thickness) as decorative motif
+- **Extreme bold titles**: 56-64pt titles with textFill gradient fade
+- **White card panels**: Elevated rect panels (roundRect) with content on dark background
+- **Small section labels**: 9-10pt uppercase labels for hierarchy
+- **Alternating layouts**: Dark-full → white-card → stat-hero pattern creates rhythm
+
+## Key Morph Patterns
+
+- White panels morph in size and position across slides
+- Grain texture stays consistent (organic continuity)
+- Sparkle crosses reposition as decorative accents
