# Third-party notices The Attune website adapts code from three MIT-licensed libraries, bundles MIT-licensed npm packages and self-hosts three fonts under the SIL Open Font License 1.1. Everything else (layout, styles, light rig, icons, diagrams and copy) is original to this site. The placeholder mark comes from Attune's own design kit (`design-kit-oct19/preview/assets/attune-mark.svg`). ## Adapted source code (MIT) ### Componentry: scroll choreography - Upstream: https://github.com/harshjdhv/componentry, commit `b602c2872fea85c9f2464016ce3bbe0af17b51b4`, file `packages/ui/src/components/scroll-choreography.tsx` - Used in: the "How it works" sequence. - `src/islands/sequence/Choreography.tsx`: the tall track with a sticky frame, `useScroll` with the offsets `["start start", "end end"]`, the same `useSpring` settings (stiffness 400, damping 50, mass 1.2) and piecewise `useTransform` keyframes with holds. - `src/islands/sequence/sequence.css`: the track and sticky frame rules (`.chor`, `.chor__sticky`). - The port comes through design composition B (`compositions/b-forest-stage/src/components/sequence/Choreography.tsx`), which changed it to seven stages with plateaus, measured positions, stage keys and a moving key light. ``` MIT License Copyright (c) 2026 Harsh Jadhav Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
