# Third-party content in GG Motion

Motion exposes GG-authored skills and craft references. The old upstream
creative/workflow skills and guidance adapters have been removed. Retained
technical references are adapted for GG's pinned launcher and local-only safety
boundaries; do not restore entire upstream skill folders when updating the
runtime.

## Content boundaries

Motion ships no templates derived from third-party After Effects or other
motion projects. The earlier Mixkit, Mobile Notification and Kinetic Text
reconstructions were removed on 2026-09-29 and are not part of any release.

Existing `references/index.json`, signal sources and compact temporal JPEGs are
GG studies, not private user videos or a universal style. They remain optional
implementation/reference assets, not a mandatory research workflow. Previews are
rendered offline by `scripts/build-motion-references.mjs`; existing library/font
licenses remain with their sources.

The Motion-only preference reader and review tool do not load Coder instructions.
Review remains bounded and tied to current source/render evidence. It checks the
video's plan and approved inputs, not a competing art direction, and does not
claim full playback or aesthetic certification from model image critique.

## Fonts

19 families, listed in `fonts/fonts.json`. Latin-subset variable woff2 as served
by Google Fonts, except Mona Sans, Hubot Sans, Short Stack and Finger Paint: they
carry OFL Reserved Font Names and ship as complete upstream fonts, recompressed
to woff2. Unbounded, Sora, Short Stack and Finger Paint were added 2026-09-29. `fonts.mjs add`
copies each family's `OFL.txt` into the video project with its font files.
