Convert existing single share class into tiered structure. “Senior shares” receive priority claim on any dividend or profit distribution but carry no voting rights. “Junior shares” retain voting power but absorb first losses. Shareholders can convert between classes, creating strategic decisions about whether you want control or security.

Dev Requirements:

• Database schema update for share class types
• Conversion mechanism with cooldown period
• Updated dividend distribution logic (waterfall)
• Portfolio view showing class breakdown
