Senior designer plan review. Rates each design dimension 0-10, explains what
would make it a 10, then fixes the plan to get there. Covers information
architecture, interaction state coverage, user journey & emotional arc, AI
slop risk, design system alignment, responsive & accessibility, and unresolved
design decisions. Writes findings to DESIGN_REVIEW_<ref>.md in the project
root.
Use when the user says "design review", "/design-review", "review this UI plan",
"review the design", "is this design intentional", "rate the design", or before
implementing new UI screens / user-facing flows / design-system changes.
