{{-- Authenticated panel shell: collapsible sidebar + sticky topbar + theme toggle + language switcher. The panel brand seed is injected into :root so the whole primary-* scale re-themes per reseller. The wordmark and browser-tab title read ONE source — App\Support\Brand::name() (the owner/current panel name) — the same value Settings → General writes. A small listener below keeps them in sync live when that name is edited, so a rename shows without a reload (Livewire re-renders the component, not this layout). --}}
