/*
 * Design: "the ledger" — this app's one job is putting a human signature
 * between an autonomous agent and anything irreversible (money, publishing).
 * Every pending item reads as an entry awaiting authorization, not a
 * generic table row: monospace for anything numeric or identifying (so it
 * reads as exact and auditable), a brass "awaiting signature" accent,
 * forest/brick for money in/out, and a torn ledger-line before every
 * decision.
