/* SalamaTalk shared auth/landing stylesheet - v3 design system.
   Used by login, login_2fa, password_reset, reset_2fa, join and register so
   every entry page is literally the same design system.

   Dark (default): silky black - a near-black satin base (#0a0a0c) with a soft
   sheen, graphite cards lifted by neumorphic dual shadows, and warm creme
   (#f2ecdd) taking the place of white for ink, highlights and primary pills.
   [data-theme="light"]: pastel light - soft powder-blue/pink paper, white
    cards, ink-black type and ink pills, classic light neumorphic shadows.
   Legacy variable names are kept because the page markup still references
   several of them inline. Type is Plus Jakarta Sans (see /static/fonts.css). */
