Function generate_single_spec

crates/csskit_spec_generator/src/main.rs:73–100

Generates code for a single spec by processing all its versions Accumulates properties from all spec versions, with later versions overwriting earlier ones for properties with the same name, then generates a single Rust module containing all the property definitions.
