/* ===========================================================================
   Sputnik X — Trade Explorer 3D (plan §5 D2-D5)

   Dark premium console, same visual family as /memory-center (glass panels,
   #0a0e16 space background, cyan primary) + /data-chat (LV operator chrome).
   Plain hand-written CSS — no Tailwind build step, no CDN, no webfonts.

   Pieces:
     1. shell + header          — fixed top bar with window/count chips
     2. #te-graph-host          — WebGL host filling the viewport
     3. .te-legend              — top-left glass legend
     4. #te-gate                — auth gate overlay
     5. #te-info                — right slide-in node panel
     6. #te-halos               — anomaly / chat-focus halo rings overlay
     7. .te-chat                — bottom-left chat dock
     8. .te-tip                 — hover tooltip card (FG3D label layer)
