What made the cut
Formal “What a gem” callouts plus gems the book actively recommends or reaches for in its examples. Left out on purpose: cautionary examples (a DSL shown as a query pitfall, schedulers shown as an anti-pattern), pure framework plumbing described in passing, and libraries named only to illustrate a category rather than endorse it.
