/*
 * The Ledger — chart-room aesthetic.
 *
 * The cockpit is amber CRT; this is the navigator's chart room of the
 * same ship. Brass + navy ink, parchment in light mode. No glow, no
 * scanlines, no Share Tech Mono. Numbers are tabular; rules are
 * hairline; the room is quiet.
 *
 * See .kt/spec-ledger.md section 8 for aesthetic intent.
