/* Signal Dark — INSIGHTS screen styles (P4, epic #1525)
 *
 * Ported VERBATIM from tests/parity/mockups/pwa-redesign.html section 07.
 *
 * CSS classes lifted:
 *   .mast             — shared masthead (defined here for self-containment;
 *                       same rule as garage.css — harmless duplicate, same value)
 *   .bignum           — median price hero block with market-trend callout
 *   .ichart           — area/line chart + axes
 *   .mvrow            — top-movers rows (make + price delta)
 *   .segrow           — segment rows (body type + median + bar + delta)
 *
 * Shared atoms (.frame, .sb, .sect, .shd, .fnav, design tokens) live in
 * signal-dark.css and are NOT redefined here.
