Telegram-style "delete for everyone" in the example app: a dark-theme group chat mock (long-press context menu, reactions, confirm sheet) where the deleted bubble is snapshotted with react-native-view-shot, bound as a ShaderView texture and dissolved by a fragment shader into particles that sweep left to right, drift up-left and fade. The snapshot and canvas are prepared on long-press so the swap is seamless; the lifted message settles back before dissolving and the remaining rows slide into place with a Reanimated layout transition.

React Native types View as a function component, so useRef<View> and a View-typed parameter have no measureInWindow; use ComponentRef<typeof View>. Unblocks the repo-wide typecheck that has failed on main since #30. Claude-Session: https://claude.ai/code/session_01MYgJDumHFGETXWCh37fS7V

Problem
The example app had no "sample a real view into a pixel grid" effect. Telegram's delete-for-everyone dissolve is the canonical one, and it needed a convincing Telegram chat around it.
Approach
Dark Telegram group-chat mock with long-press menu and confirm sheet. The bubble's content layer is snapshotted with react-native-view-shot, bound as a ShaderView texture, and a fragment shader sweeps it into particles on a smooth invertible wind field with a bounded cell gather.
Tests
