APIs you can click

This chrome is a nested layout chain. Desk pages sit in two shells; Motion only uses the outer one. Sibling navigations keep parent controllers mounted.

resource + reconcile

resource fetches an abortable snapshot of the shared task list. reconcile patches real DOM nodes by key — no virtual DOM.

const box = resource(async (_src, signal) => { await delay(180, signal); return liveTasks.value.map(item => ({ ...item })); }); this.effect(() => { reconcile( this.listEl, liveTasks.value, item => item.id, item => { const li = dom.create('li', { class: 'live-item' }); li.append(dom.create('span', {}, item.title)); return li; }, (el, item) => { const title = el.querySelector('span'); if (title) title.textContent = item.title; } ); }); this.on(this.refreshBtn, 'click', () => box.refetch());

Add a task on the Form page, then come back. The outer shells stay put; only this outlet is replaced.
