/* Listing Staging - public marketing site.
 *
 * Deliberately not the app's stylesheet: this page is a normal browser document,
 * signed out, indexable, and served straight off nginx. No safe-area insets, no
 * standalone-mode compensation, no imported font - the app under web/src/ owns
 * all of that, and importing any of it here is how the two surfaces converge.
 *
 * The type stack is system serif + system sans on purpose. A marketing page that
 * blocks its own largest paint on a third-party font request is slower than one
 * that does not, and Palatino/Iowan ships on the machines listing agents use.
