/* Demo page chrome only.
 *
 * Everything inside a panel — the tables, the blotter rows, the watchlist, the
 * icon buttons, the P&L colours — is styled by the package's own
 * styles/trading-controls.css. This file styles the page around them and does
 * one thing to the controls themselves: it re-declares the --t-* tokens.
 *
 * That is the documented way to re-skin the package (styles/theme.css says so in
 * its own header: "a host with its own brand does NOT load this file — it
 * declares the same custom properties itself"). We still load theme.css, so any
 * token this file forgets keeps a working default, and we override the handful
 * that carry the look — pointing them at the palette of the sschart demo so the
 * two demo pages read as one family.
 *
 * The board itself is dockview-core. Its stylesheet paints from --dv-* custom
 * properties, so the dockview chrome is re-pointed at the same --t-* tokens
 * below — one theme attribute flips the page, the panels and the dock together.
