facett-file/tests/render.rs

//! **CPU render-proof for facett-file.** The inline tests cover `human_size`/icon
//! helpers + the remove-intent state; the `Files::ui()` render path (the drop zone, the
//! attachment rows with icon/name/size, and the 🗑 remove buttons) is never executed.
//! This drives real `egui_kittest` frames so the painter runs and the list rides into
//! the AccessKit tree — read-write **and** read-only.
