-compileability). Then make the red gate LOUD: build-web has been failing
+Fix as shipped (2026-07-17): two moves. (1) `anim_mixer` is UN-gated in
+`lib.rs` — it is pure per-instance state embedded in the always-compiled
+`ModelAnimation`, no heavy deps; gating it was wrong to begin with
+(models3d exists to drop gltf/image_dds, not mixer math). (2) Everything
+that actually touches the optional deps — the `load_gltf*` family and its
+private helpers, ~1,200 lines — moved to a new `models_gltf.rs`, included
+from `models.rs` as a single `#[cfg(feature = "models3d")]` module; the
+four `ModelManager` loader methods carry the same cfg. All FFI call sites
+already had feature-off stubs, so no surface changed. Side effect: the
+split takes `models.rs` from 2,346 to ~1,090 lines, retiring its EN-052
+grandfather entry in `tools/file-lines-baseline.json`. Verified: wasm
+`--features web` (the failing check), wasm `web,models3d`, and native
+default all compile. Still open from this ticket: make the red gate
+LOUD — build-web was failing
 for ~10 hours and five merged PRs without anyone noticing, which is the
 EN-058(a) lesson again — a gate nobody reads is not a gate.
