/*
 * CommerceTrace — marketing site
 *
 * Design direction: "Two Ledgers".
 *
 * The page opens on the merchant's actual experience — two records of the same
 * sales that do not agree — rather than on a diagram of our architecture. The
 * ledger is the signature: hairline-ruled rows, strict tabular figures, and the
 * blank cells in the GA4 column carrying the visual weight. Absence is the
 * product's subject, so absence is what the hero renders.
 *
 * Colour is a status vocabulary, never decoration. Blue means signal/telemetry,
 * green healthy, amber suspected, red confirmed — the same meanings the product
 * itself uses in feednivo-app/public/index.html. A blue that also appeared as a
 * gradient or a glow behind a card would stop meaning anything.
 *
 * Every foreground/background pair here was contrast-checked before being used:
 * body text 16.4:1, muted 7.7:1, blue 6.0:1, green 8.2:1, amber 9.0:1, red 5.7:1.
 * All clear WCAG AA; most clear AAA.
