▪ The reality of “learn once, write anywhere” after 10 years of React Native

▪ Code sharing percentages: how much is realistic, and where native code still matters

▪ Platform-specific trade-offs: mobile vs. web vs. desktop vs. TV

▪ Supporting multiple input modes, screen resolutions, and performance constraints

▪ Brownfield challenges and bridging native functionality at scale
