The finished prompt

Write a grounded alternate history.
### The change
Point of divergence: On the night of the Union Carbide MIC release, the scrubber and flare stay dead, the water curtain is ineffective, and a temperature inversion holds the methyl isocyanate cloud low over dense neighborhoods for longer.
When it happens: 2–3 December 1984
Where / who it hits first: Bhopal, Madhya Pradesh, India
### How to write it
- Style: documentary alternate history, precise, grim, grounded in industrial chemistry
- End the timeline in: today
- Zoom in on: immediate deaths and blinding, long-term health and legal fight, Union Carbide/Dow, Indian industrial regulation, and whether other MIC plants worldwide shut sooner
- Hard rules: This is a toxic-gas disaster, not radiation. Do not import Chernobyl language. Extra deaths come from exposure time and population density, not from a new invented toxin.
### Method
1. State the real baseline in 2–4 sentences so the fork is clear.
2. Make the divergence small and mechanical — one failed action, one different decision, one piece of luck that goes the other way. Do not stack extra miracles.
3. Follow first-order effects (hours/days), then second-order (months/years), then the world as of today.
4. Keep physics, logistics, institutions, and incentives intact unless the divergence itself breaks them. No cartoon apocalypse unless the change actually implies one.
5. Mark speculation vs established fact. If numbers are uncertain, give a range and say why.
6. Say what does **not** change. Most of ordinary life continues.
### Structure
1. The day of the fork
2. The following weeks
3. Year 1
4. The next decade
5. Long tail to today
6. What still looks like our world
7. One-paragraph verdict: how this timeline differs, and how it does not
Be specific about dates, quantities, and institutions. Do not turn the story into a single-theme sermon.
