/*
  KMS site — production layer.
  Tokens and component classes (.btn, .card, .tag, .input, .table, .blueprint,
  .duotone, etc.) come from /theme/kms-theme.css — carried over literally
  from the design handoff. This file only adds page chrome: header, footer,
  hero, listings, filters, part detail, and the placeholder-photo pattern.
  Nothing here hard-codes a color, font or spacing value the tokens
  already provide.
