This is your companion for moving a Tailwind project from v3 to v4 without breaking the visual output. Run the official upgrade CLI first, then apply this for the patterns it misses: consolidating verbose classes, killing @apply overuse, replacing arbitrary values with tokens, and modernizing syntax. It's organized into 50 rules across 8 categories with clear priorities, from critical config migrations to optional modern features like container queries. The architectural guidance is solid, especially the advice to reserve Tailwind for primitives and compose at the domain level. If you're doing a major version migration or inheriting a messy Tailwind codebase, this gives you a systematic cleanup checklist.
