# Typical loading
Post::with(['author', 'tags'])->withCount('comments')->paginate(20);
# Constrained eager loading
User::with(['posts' => fn($q) => $q->latest()->where('published', true)])->find($id);
# Pivot ops (many-to-many)
$post->tags()->sync([1,2,3]); // atomic replace
$post->tags()->syncWithoutDetaching([4]);
# Chunking large reads
Order::where('status', 'open')->lazy()->each(fn($o) => ...);
