C++ programming style

1. No naked pointers

   • Keep them inside functions and classes
   • Keep arrays out of interfaces (prefer containers)
   • Pointers are implementation-level artifacts
   • A pointer in a function should not represent ownership
   • Always consider std::unique_ptr and sometimes std::shared_ptr

2. No naked new or delete

   • They belong in implementations and as arguments to resource handles

3. Return objects “by-value” (using move rather than copy)

   • Don’t fiddle with pointer, references, or reference arguments for
