Create a 20-second vertical (1080x1920) pixel-art video for Swarm Pepes, a fully onchain Pepe NFT collection on Ethereum (contract 0x999ce0ce8c5f7661e0c74a568ffe27ceb9177bdb).

Use the same visual style as our previous Swarm Pepes videos: retro 8-bit pixel art, dark background, neon green CRT glow, subtle scanlines, chiptune soundtrack.

Message: "IMD mainnet is coming", with a teasing hint at coins.

Beats:

1. (0-4s) Darkness. A single pixel Pepe flips a small glowing gold coin into the air with his thumb, catches it, flips again. Soft "ting" sound on every flip.
2. (4-10s) More Pepes appear one by one in a grid, each spinning or flipping their own pixel coin, different skins and hats, all in sync with the beat. The coins have a simple blank face with a tiny "?" on them.
3. (10-15s) The coins start rising and merging into one big spinning coin in the center. The CRT screen flickers, a progress bar labeled "testnet → mainnet" fills up to 100%.
4. (15-20s) The big coin stops spinning, facing the viewer, glowing. Text appears: "IMD mainnet is coming". Small text below: "swarmpepe.xyz". Last frame: one Pepe winks and pockets a coin.

Keep the coin design generic and mysterious (no real token logos, no price numbers, no promises of returns). No real people, no other brands.
