/**
 * Section 199A QBI Deduction Estimator — 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 .qbi. QuickBooks-style: an
 * input column beside a results column with a live zone meter, a three-card
 * summary, and a breakdown grid. Mobile-first; two columns at ≥860px. Print too.
 *
 * The A/B/C meter segment widths are fixed because the 2026 OBBBA thresholds and
 * phase-out widths share the same ratio for Single and MFJ (threshold : width =
 * 2.69 : 1), so the segment proportions are identical for both filing statuses.
