Ah, that detail actually adds more insight into the psychological and physiological reasoning:

1. Consistency = control: After trauma, a person’s sense of control is often shattered. Choosing identical stars (same design, same color) can be a subconscious way to create order and predictability. The brain finds comfort in uniformity because it signals stability and reduces cognitive or emotional “chaos.”
2. Reinforcement of meaning: Having three identical stars strengthens the symbolic significance of each one. Rather than each star representing something different, the repetition amplifies the idea—whether it’s hope, resilience, or milestones in healing. The brain often responds more strongly to repeated symbols.
3. Aesthetic satisfaction: Humans are neurologically wired to enjoy symmetry and patterns. Identical designs produce a sense of harmony, which can soothe anxiety and create a subtle feeling of control over one’s environment—even on the body.
4. Focus on the symbol, not variation: By keeping the stars the same, the meaning of the symbol itself (guidance, light in darkness, survival) becomes the focus, rather than any visual differences. It’s a way for the brain to anchor to one comforting idea, especially after trauma.
5. Safety and predictability: The uniform design can act as a safe, reliable marker of identity and recovery. After trauma, the brain craves things it can understand and predict, and identical symbols fulfill that need subconsciously.

In short, the identical stars aren’t just aesthetic—they reinforce control, harmony, and a clear symbolic meaning, all of which help the mind recover from trauma.
