Defects 1 (logo) and 2 (close-X overlap) fixed and tested. Defect 3 (WorkspaceSwitcher) audited as already-correct full-height flex column with a min-h-0 guard; not device-verified, dynamic-viewport-height flagged as the remaining suspect. Records the resolution per the GRADIENT-BRAND-ALIGNMENT convention. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
