	// This is a minimal drop-in replacement (same constructor signature and the
	// inherited `.value` uint property used everywhere in this codebase) so the
	// component compiles and the rendering-layer filters still work as plain
	// bitmasks. It draws as a generic uint field in the Inspector rather than the
	// specialized Rendering Layer Mask picker Unity 6 provides - you'll type the
	// bitmask manually (or wire your own PropertyDrawer) rather than pick names
