Overview

Thin wrapper returned by ‘Rangeable#[]`. Wraps the active-element list at a single coordinate so we can grow the surface (e.g. add `count`, `transitions`, etc.) without changing the public type.

‘objs` is always a frozen `Array` of elements ordered by first-insert `ord(e)` ascending (RFC §4.5). We use a `Struct` (rather than a plain class) because the hot-path call sites are `r.objs` and the Struct accessor is materially faster than going through `attr_reader` + an ivar in MRI.
