/* PVV v5 — Scenarios widget ("What changes if…?" Mode 3).
 *
 * Layout notes:
 *   - Side-by-side comparison table uses CSS grid with one column per
 *     scenario (baseline + each variant). On narrow screens (<720px)
 *     the grid collapses to a single stacked column per row.
 *   - Delta highlighting uses coloured left-borders:
 *       amber  = benefit amount changed
 *       red    = eligibility flipped
 *       slate  = no material change
 *   - The widget respects the plain-language toggle (pvv-standard /
 *     pvv-simplified) and caregiver mode (pronoun swaps happen after
 *     our render pass, via pvv-caregiver.js's DOM walker).
