Money forecast: calm optimistic start, rising plateau, thin solid projected lines

- Optimistic: no crash or correction through 2031 (5 years from today), earning the
  9.5% average; cycle resumes after (correction 2035, crash 2040). Salary plateau
  grows 2%/yr real so pay never stalls.
- Realistic keeps its single -30% crash in 2029; pessimistic unchanged.
- Projected lines are now thin, slightly lighter solid lines in every view; legend updated.
- Explanation text lists the crash/correction years and recovery time.
