   Tokens measured off smartweldai.com on 2026-09-15 (station-8 plan). Real brand
   assets from the owner supersede these values if they ever arrive.

   Load order in an app: bootstrap.min.css → brand.css → the app's own css. This
   file re-themes Bootstrap through its CSS variables, so existing markup
   (btn-primary, table, alert, form-control) takes the brand without rewrites,
   and adds the .sw-* shell classes both business surfaces share.
