+# Swiss System — Pure Black and Red
+
+## Style Overview
+
+Pure white background with ink black and fire red only. Features !!rule actor (full-width rect) that sweeps vertically across slides, creating dramatic transformations.
+
+- **Scenario**: Corporate, finance, consulting, high-end professional services
+- **Mood**: Clean, systematic, bold, Swiss design
+- **Tone**: White with black and red accents
+
+## Color Palette
+
+| Name       | Hex     | Usage                    |
+| ---------- | ------- | ------------------------ |
+| Background | #FFFFFF | Pure white               |
+| Ink        | #000000 | Black for text and rules |
+| Fire       | #FF0000 | Red for accents          |
+
+## Design Techniques
+
+- !!rule (full-width INK rect) sweeps slide vertically:
+  - S1: mid-rule
+  - S2: top thick
+  - S3: bottom thick
+  - S4: thin center
+  - S5: wide top-third band
+  - S6: full INK inversion (CTA - entire slide becomes black)
+- Zero darkness until final CTA slide
+- Swiss design principles: grid, typography, minimal color
+
+## Key Morph Pattern
+
+The !!rule actor creates a dramatic journey from subtle horizontal line to complete slide inversion, representing transformation from light to dark, question to answer, problem to solution.
