## Creative invariant

Preserve the slab geometry, code palette, syntax-token layout, camera pose and original 8 s timeline.

## Story and replacement contract

A configuration loader becomes an illustrative video-cutting function.

Replace the displayed function, variable and call tokens. The code is visual copy, not a callable OpenMotion API.

## Timeline and format

8 s composition; syntax is rasterized into a texture, then mapped to an extruded slab and moved on the existing timeline.

Canvas: 1920 × 1080; full composition: 8 seconds. Comparison excerpts use a shared source-time range on both sides. They are silent; no music, voice or audio fidelity is claimed.

## Material requirements

This preset uses the supplied code, type and artwork. No paid generation service is required. The materializer copies pinned scripts, fonts, textures and the reference video into the output project and rewrites CDN/font URLs locally. Custom fonts must be supplied as local files. For a personal adaptation, supply approved copy and any requested brand replacements.

## Review

Keep the line count and syntax-color tokens. Shorter or longer identifiers can change texture width and must be checked for clipping.

Compare matching timestamps: entrance, main hold and exit. Record source hash, exact preset, render environment, output file and observed problems. Source reuse proves this content substitution can preserve the implementation; it does not prove arbitrary video reconstruction, a similarity percentage, or audience performance. See the pack's evidence manifest for checks actually completed.
