Overview

Generates a shareable MP4 of a project's showcase. The showcase HTML is written first (it is the render input and stays useful on its own), then headless Chrome and ffmpeg turn it into one seamless 1080p camera loop. The toolchain is checked before any indexing so a missing browser or ffmpeg fails in under a second with install guidance.

DEFAULT_CLIP_NAME =

MARKER_SCAN_HEAD_BYTES =

faststart parks the metadata (and so the marker) right behind ftyp, so every clip RubyLens writes matches within this head window.
