/**
 * Variant CSS: pricing--trio-hairline-columns
 * Layer 2 — Path B pricing role (brief-bound, Element Count 3, 2026-06-10).
 *
 * Exactly three plans laid out as three airy typographic columns separated by
 * thin VERTICAL HAIRLINE rules — no card borders, no boxes, no shadows. Each
 * column is name (kicker-ish, above) → big price (the hero) → muted one-line
 * tagline (below). The only decoration is the 1px divider between columns.
 *
 * Distinct from three-tier-cards (separate, elevated cards each with border +
 * radius + shadow): here there are no cards at all, just clean columns divided
 * by hairlines, reading editorial and minimal with the price up front.
 *
 * The tier container is a wp:group grid layout; CSS pins it to an explicit
 * 3-column grid so the trio is deterministic. Hairlines are drawn as
 * border-inline-start on tiers 2 & 3 (never the first). Below 780px the layout
 * collapses to a single column and the dividers switch to horizontal
 * (border-block-start) between stacked plans.
