/**
 * Variant CSS: offer--duo-split-diptych
 * Layer 2 — Path B universal offer variant (authored 2026-06-10).
 *
 * Concept: EXACTLY two services as a balanced diptych — two tall 50/50 panels
 * stitched by one shared vertical seam (the diptych "spine"). Each panel carries
 * a big index numeral (01/02), an accent top hairline, an icon chip, a title, a
 * fuller description and an outline "learn more" link. The SECOND panel sits on a
 * subtle accent-tinted surface so the duo reads as a contrasting pair, not a
 * pricing comparison. Built for Element Count: 2 (the list rebuild keeps two).
 *
 * Differentiator vs sibling EC=2 offer variants:
 *   - duo-rows: two full-width stacked rows, big numbers, NO cards, vertical rhythm.
 *   - two-tier-packages: two PRICED tiers with check-lists + "most chosen" badge.
 *   THIS one: two equal portrait cards sharing a centre seam, one accent-tinted.
 *
 * Colour intent: text stays --ink (polarity-aware on the light surfaces); numerals,
 * icon, top rule + hover take --accent. The accent panel uses a faint --accent
 * wash so it never becomes a dark band (text contrast stays comfortable).
 * area-1-* / area-2-* tokens: title, desc, link text.
