The PNG files are the production source of truth (AI-generated, no hand-authored SVG equivalents). The legacy "three-node + friendly face" identity (including its *-halo-node-v3.svg sources) was removed from the site; regenerate or derive variants (e.g. new sizes, taglines) with image-to-image from the mark/lockup PNGs above.
