PRFCategoryChips<T> class

A generic, reusable category chip selector widget.

Renders a horizontally scrollable row of chips, one per categories item, plus an optional "ALL" chip. Selecting a chip calls onCategorySelected with the item — or null for the "ALL" chip.

Usage:

PRFCategoryChips<MyCategory>(
  categories: myCategories,
  selectedCategory: _selected,
  onCategorySelected: (category) => setState(() => _selected = category),
  labelBuilder: (category) => category.name,
)
