Making life easier with Derive and other tools
summary
Uses derive macros (syn, quote, synstructure, darling) to generate hundreds of repetitive implementations across 362 CSS properties, replacing hand‑written match/serialize/compute code and removed 4,000 LOC from Servo. Builds a procedural macro that emits serialization and has‑viewport‑percentage logic per enum/field, finds real bugs (missing spaces in serialization), and implements an inert crate that auto‑generates neutralized wrappers so single‑threaded RefCell data can be accessed from layout threads without ad‑hoc unsafe code.
