/* ============================================================================
   style.css  --  "What Can I Learn About You?"
   ----------------------------------------------------------------------------
   A deliberately old-web stylesheet. Target era: 1999-2005.
   Black CRT background, phosphor-grey text, cyan links, purple visited links.
   Borders, tables, horizontal rules, blinking cursors. No rounded corners,
   no shadows, no gradients, no modern anything.

   Palette
     background .... #000000
     text .......... #D0D0D0
     link .......... #00FFFF (cyan)
     visited ....... #B24BF3 (purple)
     success ....... #00FF00 (green)
     warning ....... #FFFF00 (yellow)
     danger ........ #FF0000 (red)
     dim border .... #333333 / #00AA00 (terminal green)

   Font: VT323, falling back to Courier New / Lucida Console / monospace.
   VT323 is loaded via header.php (Google Fonts). If offline, the monospace
   fallbacks keep the whole thing readable.
