Visibility reduces search time
A single row or shallow zone makes missing items obvious.
Deep storage needs sub-zones
Pull-forward trays or bins are easier than loose second and third rows.

Stacking works better for identical or low-use items than mixed daily supplies.

If returning an item requires moving three other objects, the system is fragile.
Practical boundary. Measure first, respect product load limits, and do not improvise wall, ceiling or overhead installations when the structure or appropriate hardware is uncertain.
