Deep category levels are hard to scan — Elektrik has 62 children, Kaporta 58.
Add a name filter input that appears when a level has more than 8 items and
filters the current drill level live (Turkish-aware lowercasing for İ/ı), with a
clear button and a "no match" message. Resets automatically when navigating
between levels. Benefits the vehicle, catalog, and category sub-page flows since
they all share CategoryGrid.
