1//! Data containers — role-agnostic column storage definitions.

3//! Role assignment (X / Y / X-error / Y-error) lives in
4//! [`crate::data_config::SeriesConfig`]; `Column` / `DataCell` themselves are
5//! role-agnostic. The upload adapter (`ColumnSource`) is the renderer's
6//! concern and lives in the renderer crate.
