/*
 * delegation.css — Track N · Delegation Graph + Budget Simulator (V4)
 *
 * Page-specific layout on top of Track A's tokens (styles.css).
 * Implements the two-column Civic Candor delegation surface:
 *   Left  — topic delegation table + cumulative alignment + override-pending banner
 *   Right — participatory budget simulator: donut SVG + slider rows + audit receipt
 *
 * Design ground rules (PRD §6 + track-n.md §10):
 *   - All colours via var(--token). Zero hardcoded hex/rgb values.
 *   - 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
 *   --highlight
 *   --rule, --rule-soft
 *   --serif, --sans, --mono
