omena-transform-target
omena-transform-target maps a target feature matrix to target-sensitive
transform passes. It keeps target lowering explicit: opt-in flattening passes
stay blocked unless the caller enables them, and final ordering is delegated to
omena-transform-passes.
Browser thresholds that are not fully covered by the embedded browserslist
snapshot are reviewed data, not inline code. The crate reads
data/browser-thresholds.toml and validates data/pass-feature-bindings.toml
so target-sensitive passes stay tied to explicit source quorum and pass IDs.
