/* ─────────── TESTIMONIALS (signed page) ─────────── */
/*
 * Concept: each testimonial is a signed page from a ledger.
 * Quote opens with a tall serif drop-cap in the accent colour;
 * a single hairline above the byline turns name + role into a signature.
 * Brand W-glyph sits low in the corner as a watermark. No box, no card —
 * two hairline rules frame the page; the typography is the architecture.
