The compiler turns a component declaration into: - a record of its props and state; - a constructor, a props setter, a model and a call; - a class, registered with ludic.ui at start. Its template and styles are read from beside it and compiled in, with @import inlined, and a missing template fails the build. In the runtime: - each mounted instance keeps its own props and state, and `set` in a template writes the state; - styles are scoped to the component; - class, style and id on a component's tag land on its root, styled by the parent's sheet too; - ui_reload re-reads a component's files from disk and keeps instances. The package's own module is now ludic_ui, so a program may call a directory of its own ui. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# reload.ludic - a developer's templates and stylesheets read again when they change on disk: every

# file is re-read in the order it was first loaded (so an import is there before its importer), and

# the screens' state is kept, as React's fast refresh keeps it. True when anything changed.
