axumweyane/blender-shorts ? reverse-engineered prompt

Build me a headless Blender tool that turns a narration JSON file into a vertical YouTube Short in the style of Zack D. Films.

I want it to render a 1080 by 1920 MP4 with a dark navy gradient background, big kinetic typography, and beat by beat text reveals. The text should type on letter by letter, slide up, and fade in, with auto resizing so it never spills off the frame. Add drifting snow particles, a little camera zoom on important beats, and a brief screen shake when a line is meant to hit hard.

It should run from the command line with Blender in background mode, so I can point it at a JSON script, choose an output file, and set the duration. I also want a small MCP wrapper so I can trigger renders from Claude Code as a tool. Use the example narration files as a guide, and if you need current Blender or MCP details, look them up online.
