summary

Live coding in VS Code demonstrates exact patterns and working code: using map types and template literal types to auto-generate every margin/padding key, intrinsic Capitalize to add an onX prefix, recursive generics to build fixed-length Tuples (with the compiler hard stop around 999), infer to extract nested Promise/array types, never + satisfies to force exhaustive switch checks at compile time, and branded types plus assertion guards to make a true Email string. A small CSS/arithmetic validator and a VS Code TypeScript Worksheet plugin are shown and run successfully.
