   VetMyVin — "The Appraiser's Ledger" design system
   Paper + ink + mono numerals. Numbers are the design; everything else is
   the paper they're printed on.

   CONTRACT: every class that existed before the redesign keeps working —
   guides/terms/privacy reference these with frozen HTML:

   .moderate .minor .good .info) .tiny .center .result .tr-row .neg .grid

   .row .photo-btn .sell .pricing .verdict .vehicle-title .vehicle-meta
   .unlock .flag b/p .tr-window — and CSS vars used by app.js / inline
   styles: --muted --good --warn --danger --accent.
