- define missing design tokens (--card/--foreground/--accent/--font/--text-2)
that theme/modal components referenced but :root never declared (they rendered
transparent/wrong color)
- zero section-panel padding so .signal-header is the single top-spacing source
(was double 22px+22px on theme/lineage/health/sim/backtest panels)
- theme cards now surface the new source reads (banks rate, retail sales YoY,
nonbank household debt, property prices, telecom business confidence)
