 * Filament's auth pages are a card centred in an empty page. This turns that into a two-column
 * screen: the College on the left, the form on the right. It is done entirely in CSS over the
 * stock markup — the only addition is the aside injected at SIMPLE_LAYOUT_START, which is the
 * one hook that lands inside .fi-simple-layout but outside the card, and therefore the only
 * place a second column can come from without replacing Filament's view.
 *
 * Plain CSS, published by `php artisan filament:assets`, because the CMS image has no Node
 * step. Loads on both panels; everything is scoped to the simple layout, which only auth
 * pages use.
