* Build: line tables only for workspace crates, no debug info for dependencies
* Tests: one integration-test binary per crate
* xtask ci: nextest, doctests, test build without examples, one wasm check
design.browseTheme reads its path with io::read_file, and File › Info sizes the file with
io::file_len (which checks the read root), so commands_do_not_touch_the_file_system_themselves
passes. spell.rs is allow-listed beside recovery.rs: it touches only the app's own dictionary
folders. main's render_slide MCP tool refuses a `path` argument (#371), so the root tests
render to a file through call_app ui.render instead.
