/* GoldSignals chart — app shell (forked from dtnexus-charts).
 *
 * Everything inside the chart itself is painted by TradingView's own theme
 * (driven from src/theme.js via widget.changeTheme). These rules cover the
 * header, the chart frame, the loading / error overlays and the signal panel
 * — on the same two palettes, so the seam between shell and chart is
 * invisible. The signal colours (long, short, stop, target, the level kinds)
 * are the ones the overlay draws with, declared once in src/signals/palette.js
 * and mirrored here.
