 253/-- RS perspective on e:
 254
 255    1. **No simple φ formula**: e and φ seem algebraically independent
 256    2. **Both fundamental**: φ for discrete, e for continuous
 257    3. **Connected through i**: Euler's formula, cos(π/5) = φ/2
 258    4. **J-cost requires e**: For consistent probability normalization
