🦋 DESCRIPTION 🦋

so what does she actually do? she releases a reference on the f'th paged fragment of skb. that's the tea ☕

the way that this is literally just one reference getting dropped and yet it matters so much — every ref you take, you gotta give back, periodt. it's giving responsible memory management, it's giving "i return my library books on time" energy 📚✨
