/**
 * Variant CSS: features--three-col-compare
 * Layer 2 — Path B features role (2026-06-06).
 *
 * Three feature columns set side by side with a shared header rhythm
 * (icon + tier label, then title, desc and a bulleted point list). The middle
 * column is featured — raised, accent-bordered, with a "recommended" badge —
 * giving a lightweight comparison-table read. Distinct from the two-column
 * before/after contrast, the key|value spec table and the icon-card grids.
 *
 * All selectors scoped to .universal-features--three-col-compare — no leak.
