Check the built product against my design (design QA)

Help me run design QA on a feature that has been built. Feature and spec: [WHAT IT IS; PASTE OR SUMMARIZE THE SPEC - key screens, states, tokens, and copy] Build I am reviewing: [ENVIRONMENT, PLATFORM, BROWSERS/DEVICES] My observations so far: [PASTE NOTES ON DIFFERENCES I HAVE SPOTTED] Design system in use: [NAME OR "custom"] Release date: [WHEN IT SHIPS] First, give me a QA checklist tailored to this feature covering: layout and spacing at each breakpoint, typography and token use, color and contrast, component states (hover, focus, active, disabled, loading, error, empty), copy matches spec, interactions and motion, responsive behavior and long content, keyboard and screen reader basics, dark mode if supported. Then turn my observations into tickets. For each: a short title, where it is (screen, element, breakpoint), expected vs. actual, a severity (Blocker: breaks function or accessibility; Major: clearly off-spec and visible; Minor: small polish), and a suggested fix in design-system terms (e.g. "use spacing-400, not 20px"). Only file tickets for differences I report; do not guess at issues you cannot see. Return: the checklist, the ticket list sorted by severity, and a short note to the engineer that is appreciative and clear about what must be fixed before release vs. what can follow.
