Approved design for migrating the admin frontend off ~7,100 lines of hand-written CSS onto MUI, themed to the existing brand, dark/light preserved, modern 'soft-SaaS shell + dense tables' look, rolled out incrementally (foundation-first, always shippable). Verified via 4-way adversarial review (editorial, MUI-docs accuracy, codebase-fit, completeness) with fixes applied. Also gitignores .superpowers/ brainstorm mockups.
