//! A populated `GroundView`, built for the coverage gate.
//!
//! Mid-DARVO, mid-GROUND, scored — **not** a fresh deal. Most of the
//! fields this gate exists to cover are empty at deal time, and a coverage
//! test run against a state where the fields are absent is the same lie in
//! a different costume (CB-WP-0011 T01).
//!
//! Built directly rather than projected from a `GroundState`. The
//! projection's own hiding rules are already asserted by
//! `games_ground::view` and by `cb-play`'s
//! `the_inspector_never_widens_the_projection`; re-asserting them here
//! would be a duplicated fact that drifts. What *this* crate must not do
//! is invent a hand it was never given, and that is what the renderer test
//! checks — with `hand: None` supplied deliberately.
