# 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.
