The feature existed for one reason: truck's mesh and boolean crates reach `vtkio → xz2 → lzma-sys`, a C library that cannot cross-compile to wasm32. So the web build dropped it, and with it the Model tab, solid tessellation and ACIS import — all of which quietly did nothing in the browser. cadkernel is pure Rust and has no C dependency, so none of that holds any more. The feature gated exactly two things by the end, `acis_export` and the save-path sync that calls it, and both are as portable as everything around them. Removing it means the web build makes primitives, runs booleans, draws ACIS solids read from a file, and writes them back out as exact geometry — the same as the desktop build. Verified against all three: native, `--no-default-features`, and an actual `wasm32-unknown-unknown` check rather than an assumption about one. The docs claimed otherwise in four places and are corrected. `tessellation.md` in particular was organised around whether an entity "goes through truck", which is no longer a question anything can be asked — the three paths are now a kernel B-rep mesh, a curve sampled through `entities::curve`, or geometry emitted directly, and the per-entity table is updated to match. `index.html` no longer passes `data-cargo-no-default-features`; there are no features left to turn off.
