 * QuantHub — Auros design system
 * Abyssal teal surface stack (abyss → deep → kelp), no shadows, 16px cards /
 * 6px controls, uppercase tracked eyebrows, medium-weight headings.
 * The aurora gradient is used ONLY on primary CTAs. Profit/loss use a muted
 * mint/coral pair — the one scoped exception to the teal palette, kept to
 * P/L numbers, buy/sell buttons and digit bars for at-a-glance legibility.
 * Font: DM Sans (geometric grotesque, closest free match to Matter) + JetBrains Mono for figures.
