This piece is done. Do not rewrite the body.
Give 8 titles. Each must name a recognizable problem and promise a shift. No colons. No "How to". No "The X of Y". Mark your first choice.
Give 3 openings (75–150 words): a claim, a scene, a contrast. Each must be usable as the first block; none may throat-clear.
Then: the current title and opening, and whether to keep them.
Eight titles and three openings. Do not rewrite the body.
