mobile-design-review: Audit, Score, Baseline

Report-only by default. --fix (or the user asking you to fix what you find) enables the fix loop. Never both silently.

The method is ../_shared/references/review-rubric.md (passes, narration, Trunk Test, finding format, ten categories, scoring math, baseline file) and ../_shared/references/tells.md (the grep checklist + tell catalog). Fix recommendations cite ../_shared/references/redesign-protocol.md (lever order) and sections of ../mobile-taste/SKILL.md. Read all four before starting.
