// hello-community — Phase-4 Session-5a fixture for the install-flow tests.
//
// Hand-written single-file ESM bundle (no JSX, no build step). Future
// community modules with React surfaces will go through a build template
// (Phase 5 follow-up); this fixture stays plain JS so the install-flow
// sessions can iterate without a bundler in the loop.
//
// Default export is the register(host) entry point. The host object is
// supplied by the loader at registerModule time; this module does not
// import anything at runtime.

export default function register(host) {
  host.ui.registerRibbon({
    id: 'greet',
    label: 'Greet',
    onClick: (ctx) => {
      const { id, version } = ctx.host.meta;
      ctx.host.ui.showToast(`Hello from ${id}@${version}!`, 'info');
    },
  });

  host.meta.log.info('hello-community module registered');

  return { host };
