//! **The wide roster's own bytes** (bl-0424): conversations whose *content* is
//! wider than the column, laid on the shipped world. Sibling of [`crowd`],
//! which varies the same fixture along the other axis — that one is a list too
//! TALL for the column, this one is rows too WIDE for it — and split from
//! [`super`] at §12's budget on the same seam.
//!
//! Until this existed the §11 panel-geometry beats asked their question of a
//! column whose widest row was short. `world_titled` gives one row a long
//! title, and a title truncates correctly and always did; nothing in the suite
//! gave a row a long title **and** a preview beside it, which is the pair that
//! reproduces the operator's report — the preview is laid after the greedy
//! title, so a title that fills the row leaves it zero width, and a run laid at
//! zero width still allocates its own ellipsis past the panel's edge. That
//! allocation is what egui stores as next frame's panel width.
//!
//! [`crowd`]: super::crowd
