   Subject: a multi-shop inventory ledger. The signature idea is the
   page reading like a physical stock ledger -- hairline rules, a
   tabular monospace face for SKUs/quantities/money, and a single warm
   amber used exclusively for "needs attention" (low stock, expiring,
   alerts) so it carries real meaning instead of decorating everything.
