/*
 * "Trade Gold" redesign (2026-09-23) — replaces the plain beige/navy theme
 * with the palette/typography chosen from the UI direction concepts
 * (navy #013090 + gold #C9962B on an ivory ground, Poppins), a left
 * sidebar in place of the old topbar+dropdown nav, and card-grid list
 * screens wherever a table was hard to scan at a glance (see
 * orders/clients/disputes index views). Every selector that existed
 * before this pass is kept — only tokens, and the handful of rules noted
 * inline, changed — so no view template needed to change just to pick up
 * the new look.

   clickable/focusable. */

   The sidebar collapses to a top strip with a hamburger toggle below
   900px — the nav + user block hide behind it exactly like the old
   topbar's dropdown did, just restyled for the sidebar's vertical
   grouping. Multi-column form grids and the new card grids both drop to
   one column so nothing forces horizontal scroll on a phone. */
