//! Per-column encoder construction.
//!
//! `Vec` wrappers are already normalized into [`crate::ir::VecLayers`] before
//! this phase. Polars folds consecutive `Option` layers into a single validity
//! bit, so the encoder collapses multi-Option access chains before emitting
//! the option leaf arm.
