/**
 * Variant CSS: testimonials--trio-stacked-rows-hairline
 * Layer 2 — Path B testimonials role (2026-06-10).
 * Exactly THREE full-width quote ROWS stacked one above the other, separated by
 * a horizontal hairline rule. Each row is led by an oversized accent INDEX
 * numeral (01/02/03) in a fixed left rail; to its right sit stars, the quote and
 * an inline name · role signature. No columns, no cards, no grid — pure
 * editorial "ledger" rhythm read top-to-bottom. Polarity-safe: --text-primary on
 * --background, --text-secondary for the role (clears AA on the section bg),
 * accent only on numeral + stars (KI-020 — never a bg token as foreground).
 * Distinct from triple-quote-marks-columns (three equal columns + vertical
 * hairlines + giant quote glyph) and from duo-stacked-rows-hairline (only TWO
 * rows, no leading numeral). Scales to a single column on mobile: the numeral
 * sits above the quote body. Every selector scoped to
 * .universal-testimonials--trio-stacked-rows-hairline (no global leak).
