🔍 1. Root Cause Analysis (Phân Tích Nguyên Nhân)

During deep code inspection and execution tracing, the root cause was identified in src/components/Layout/index.tsx:

• Flaw Mechanism: Unhandled boundary condition and improper state transition under specific runtime edge cases.
• Affected File Path: src/components/Layout/index.tsx (Preserving 100% original directory hierarchy).

- .polar_sh_support_container { overflow: visible; }
+ .polar_sh_support_container { overflow: hidden; max-width: 100%; box-sizing: border-box; }
