/* Hallmark · genre: atmospheric · macrostructure: none — functional 2-person tool, not a
   marketing/content page, so none of the 21 catalog shapes apply. Aurora's design system
   (dark canvas + two cool blooms, Geist, glow-on-hover, fade-only motion) is applied
   directly to the existing login screen + two-column tier board + modal chrome.
   theme: Aurora (no local spec file — built from the atmospheric genre's structural
   rules with a cool cyan/violet palette instead of the genre default warm amber)
