   /public/css/calc-simple-toggle.css  —  Horizontal tabs (v2)
   ─────────────────────────────────────────────────────────────────
   Replaces the vertical Quick/Advanced toggle with the cleaner
   horizontal-tabs look used on Agentic Workflow Cost.

   Backward-compatible: keeps the same HTML structure
   (.cst-toggle, .cst-active, .cst-advanced, .cst-meta) so calcs
   already using this pattern get the new look automatically with
   zero markup changes.

   To roll out: replace /public/css/calc-simple-toggle.css with this
   file and refresh the page. Existing JS handler in
   /public/js/calc-simple-toggle.js continues to work as-is.
