* tests: consolidate safe ui-egui integration targets * Group the safe UI tests as tests/ui_group/ instead of turning off test discovery With autotests = false, a test file added later builds only if someone also lists it in Cargo.toml, so new tests could silently never run. A tests/ui_group/main.rs target groups the same 15 files while Cargo keeps discovering every other file in tests/. --------- Co-authored-by: Brandon Thomas <echelon@gmail.com>

//! LaTeX `animate` PDFs (#169): every field is a push button holding a frame and a Screen
|

//! annotation drives the player. Nothing there can be filled in, so the form-fields bar stays
|

//! away, and the Screen annotation is not a comment.
