/*
 * terminal.css — Track M · Impact + Coalitions Terminal (V3)
 *
 * Page-specific layout on top of Track A's tokens (styles.css).
 * Implements the Bloomberg-style terminal: dark KPI bar, 1.4fr Impact
 * Engine | 1fr Coordinate body split.
 *
 * Design ground rules (PRD §6 + track-m.md §10):
 *   - All colours via var(--token). Zero hardcoded hex/rgb values.
 *   - Dark KPI bar uses var(--ink) background.
 *   - Three-family type stack (--serif / --sans / --mono).
 *   - No emoji, no gradients, no rounded-left-border accent strips.
 *
 * Token reference (subset used here):
 *   --paper, --paper-2, --paper-3
 *   --ink, --ink-2, --ink-3, --ink-4
 *   --civic, --civic-soft
 *   --risk, --risk-soft
 *   --support, --support-soft
 *   --rule, --rule-soft
 *   --serif, --sans, --mono
