/**
 * Common-room banners — the house-article card and the front-page hub card.
 *
 * Deliberately dark in both site themes: like the TV-show promo next door,
 * these read as cinematic plates dropped into the page rather than as panels
 * that follow the surrounding colour scheme.
 *
 * Every moving layer lives inside the card and animates transform or opacity
 * only. Nothing here is fixed to the viewport and nothing uses backdrop-filter,
 * so the card's colour never changes as it scrolls.
