 - [Phase 08-02]: User visually confirmed light/dark theme renders correctly across all 4 wizard steps — THEME-01 and THEME-02 complete
 - [Phase 09-02]: Label text inside button element (not adjacent) preserves test selector compatibility: textContent includes step name
 - [Phase 09-02]: Pre-existing TextFieldMD3.test.tsx failure scoped out — component not yet built, belongs to future plan
+- [Phase 09-md3-components]: TextFieldMD3 uses CSS-only floating label via peer-[:not(:placeholder-shown)] without JS state
+- [Phase 09-md3-components]: DEBT-01 fix: tooltip buttons use aria-label directly; RemoteConfigStep.test updated with { selector: 'input' } to prevent aria-label/label ambiguity
