/* Analytics tab (Daily electricity / Forward curves / Vol surfaces), desk-only.
   static/market-analytics.js builds every pane from document.createElement + textContent
   (tests/test_static_security.py convention) and composes the house classes: .panel,
   .panel-title, .data-table, .empty-state, .skeleton-* , .btn-ghost, rather than carrying
   copies. What follows is only what the house does not already define: toolbar layout, the
   per-region KPI card grid, table wrappers, change colouring, flag badges and chart chrome.
   Every colour is a token. Chrome is --font-sans; every number is --font-mono. Hierarchy comes
   from size, colour and tracking, never weight (house rule). */
