{{-- The B Bailey lockup, used everywhere Filament asks for a brand logo: the admin topbar, the mobile sidebar drawer, and the login and password-reset cards. Passed to ->brandLogo() as an Htmlable rather than a path, so the same lockup can recolour itself for whatever it is sitting on. The monogram ships as public/assets/img/logos/logo-mark-dark.svg, but that file bakes its fills in (navy shell, white counter) and disappears against the navy sidebar. These are the same two paths the public header inlines for exactly the same reason — see resources/views/components/site-header and the .logo-mark rules in public/assets/css/header.css — which lets CSS swap the fills instead of asking for a second asset. The mark is decorative: the accessible name comes from the wording beside it, which is why the is aria-hidden. Display only. No new route, no new query, no new asset. --}}
