/* ShipLedger landing · a printed sheet
 * mono-color: Cool Gray paper · Carbon (type, rules, CTA, one solid plate) + Ultramarine (the product, printed as duotone plates)
 *   layout   image field — the invoice blueprint rises into the headline from the right column, flush with the page edge;
 *            the finding card is a ledger slip laid over the blueprint's dissolving foot
 *   tension  diagonal · headline top-left → lede → blueprint → the ringed $96.00 bottom-right · release zone = the paper under the CTA
 *   gesture  one hand-drawn ring around the $96.00 on the finding card (broken stroke, draws once on load)
 *   process  clean plate separation for the product plates; halftone only where the blueprint dissolves into paper; 4% paper grain
 * impeccable bolder: one type scale with a real ceiling (96px / 700 display · 56px h2 · 30px rows · 17px body · 12px floor),
 *   5/12 asymmetries, one overlap (the slip on the blueprint), 1.5–3px rules, square corners, nothing decorative
 * Apple HIG: 17px body, 12px floor, no light weights, one typeface, ≥44px controls, rem throughout,
 *   interactive = carbon + underline only, Reduce Motion honored, images carry real alt text
