/* Tomebuy Spreadsheet Manifest -- kvn- prefixed design system
   Palette follows the official Tomebuy UI (brick red #C92910) and wordmark
   (cyan #00BDE0 / orange #F26E08, used only as decorative accents -- both
   fail AA contrast on white so neither carries text). Display type uses a
   self-hosted Bebas Neue; body uses the system UI stack. */
