   TRAXIUM INTELLIGENCE — MASTER STYLESHEET  (traxium.css)
   One file for the whole application. Light + dark mode.
   Tablet-first (iPad landscape 1366 x 1024), works on desktop.

   HOW TO USE
   1. <link rel="stylesheet" href="css/traxium.css">
   2. Light mode is the default.  Dark mode: <html data-theme="dark">
   3. Build pages with the .tx-* classes below (see example/index.html).
   4. Never hard-code colors in pages. Always use the var(--tx-*) tokens.

   ACCESSIBILITY RULES (non-negotiable)
   - Minimum text size 18px, labels/buttons/inputs weight 700+.
   - Text is pure dark on light, or pure white on dark. No gray text.
   - Touch targets at least 48px tall.
   - Inputs always have a high-contrast 2px border.
