# Reviewing Animations Review only animation and motion behavior. Report only: do not edit source, install packages, or turn an aesthetic preference into a deterministic failure. Use `code-review` for general source defects and `frontend-design` only after the user separately authorizes implementation. Read [references/standards.md](references/standards.md) when a finding needs a concrete curve, duration, spring, gesture, performance, or accessibility starting point. Treat those values as craft criteria that require product context and current evidence. ## Evidence Boundary Inspect the relevant diff, source, rendered interaction, frequency, input mode, motion preferences, and product motion system. Cite `file:line` when source is available; otherwise anchor the finding to a route, component, state, viewport, or recording. Separate observed behavior from inference. Do not claim dropped frames, compositor behavior, browser support, accessibility conformance, or interaction frequency without evidence. When feel is uncertain, request slow-motion, frame-by-frame, profiling, or real-device verification instead of guessing. ## Review Criteria Apply only criteria relevant to the interaction. A clue becomes a finding only when evidence connects it to user feedback, continuity, comprehension, efficiency, accessibility, performance, or product cohesion. 1. **Purpose.** Motion should orient, explain state, provide feedback, preserve continuity, or prevent a jarring change. 2. **F
