/* ==========================================================================
   ChatSphere landing page — dark theme overrides
   Activated when body has .dark-mode (set by chat-app/theme.js, which shares
   the same 'ChatSphere_theme' localStorage key as the chat + video pages, so the
   choice follows the user across the whole site).

   Strategy: re-map the CSS custom properties that landing-v25ad4.css already
   uses (--ink, --muted, --line, --bg, --card, ...), then override the few
   hardcoded light values (white gradients, #fbfdff panels, #17324d texts).
