## What it does

Composite any two HTML screens into a locked photo plate of hands holding an open foldable phone — a 1448×1086 still with two blank 495×849 / 498×849 screen slots (left and right) — to make side-by-side meme and comparison videos: TikTok vs Reels, ChatGPT vs Claude, "me vs my friend", before/after, two apps racing. Trigger on: "foldable phone meme", "put X on the left screen and Y on the right", "two-screen comparison video", "the dual-screen phone meme", or any request that names two apps/feeds/chats to show at once. The plate, geometry, and camera are finished — the agent only authors what plays INSIDE the two screens and renders.

## Use when

- Two apps, feeds or chats side by side on one phone
- "X vs Y" comparison memes
- Before/after or two versions racing

## Not for

- A single phone, a laptop or a device photo you supply
- Other aspect ratios (crop the 4:3 render as a follow-up)
