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>

# ui_component.ludic — components as files: Counter.ludic declares props, state, a field, a function
|
|
# and an event; Counter.xml is its template; Counter.lss its scoped styles (which @import a theme).
|
|
# Two counters keep their own state, a parent's class reaches the child's root, and the child's
|
|
# `p { color }` does not leak into the parent.
