//! Pins the unit blob shadow's box source against real build-5875 assets: the shadow sizes from
|
|
//! the **current animation's** `M2Sequence` CAaBox (wow-re `unit-blob-shadow.md`, `0x711a20` — the
|
|
//! same sequence-record box the pick volume and the ring's Stand-footprint read), so
|
|
//! `ModelAnimation::bounds_min/max` must round-trip the raw record. The Stand-box horizontal
|
|
//! extents of the four reference-traced creatures are already pinned by
|
|
//! `selection_ring_radius.rs` *through* the nested-sqrt footprint; this asserts the **box itself**
|
|
//! (the shadow consumes it raw: clamp ±5, scale, AA-bound — no compression). Skips when the
|
|
//! gitignored client data isn't present.
