/* ================================================================
   Heisei Twilight — landing page theme override
   ----------------------------------------------------------------
   Subtle late-Heisei (early 2000s–2010s) anime aesthetic for the
   public landing screen. Inspired by Makoto Shinkai dusk skies,
   GitS: SAC tactical UI hairlines, and CLAMP-era plate gradients.

   Scoped to `.modern-landing-page` and the floating header so the
   internal VN/contracts/daemons screens are untouched.

   Loaded AFTER pc98.css so all selectors here win the cascade.
