/* ==========================================================================
   Sign-in scene (views/login.ejs only, dark theme only)
   --------------------------------------------------------------------------
   The sign-in page replaces the beam-and-dots backdrop above (still used by
   set-password.ejs) with an "operations" scene, drawn with static inline
   SVG and CSS gradients, no images and no animation:
     1. .nx-login-scene-sky       deep navy base with soft blue light
     2. .nx-login-panels          faint, blurred dashboard screens, left
     3. .nx-login-hex             glowing blue hexagon grid, right
     4. .nx-login-net             dot-and-line network along the bottom
     5. .nx-login-scene-vignette  darkens the edges and the centre so the
                                  card keeps its contrast
   Every layer is absolutely placed by `.nx-login-bg > *`, ignores the
   pointer and sits under .nx-login-stage (z-index 1). The light theme
   hides .nx-login-bg as before, so light mode is unchanged.
