/* ── Hero backdrop (login / signup pages) ──
   The wc26-hero.svg fills the full viewport behind the login card.
   It uses a deep stadium-night palette so the light card (white bg, purple
   top border) reads cleanly on top. opacity ~0.35 keeps it atmospheric
   without overwhelming the form. prefers-reduced-motion has no effect here
   (the static SVG has no animation); the glow-pulse in the TS version is
   already gated via @media (prefers-reduced-motion: no-preference).       */
