Freeze generates images of code and terminal output.  It reads a source
file (or ANSI output captured from a command) and renders it as a PNG,
SVG or WebP image, with syntax highlighting, configurable themes, fonts,
window decorations, padding, margins and shadows.

Code is highlighted with Chroma, and JetBrains Mono is embedded by
default, so images are self-contained.  Terminal output can be captured
directly with the --execute flag.
