/**
 * Fully Burdened Employee Cost Calculator — module styles.
 *
 * Inherits the shared design tokens (--bf-primary, --bf-accent, --bf-ink,
 * --bf-muted, --bf-border, --bf-bg-soft, --bf-radius, --bf-shadow) from
 * assets/css/frontend.css. Everything is scoped to .fbc so nothing leaks into
 * the host theme. Clean, QuickBooks-style ledger feel: summary cards on top, a
 * tabbed input panel beside a four-bucket breakdown bar and ledger table.
 * Mobile-first; splits into two columns at ≥860px. Print block included.
