## Asset statement

The eight document appearances are original CSS and semantic HTML authored for this plugin. The package downloads no image, font, icon, texture, or stylesheet at runtime. Paper grain, fold marks, address lines, postmarks, stamps, redactions, perforations, archive marks, and ruled lines are generated with local CSS primitives. Harness-owned icons remain imported through its existing client UI package.

The plugin's own package license remains MIT. Consulting an AGPL project for documented observable behavior does not copy its implementation; the clean-room boundary and exact source locations are recorded in `SPEC.md`.
