/* Next Truck pages (2026-11-04): the four-page restructure from the "Next Truck Homepage" design
   canvas. Loaded after v3.css and nt-skin.css on the home page, How it works, Systems, Pricing and

   packages.css joins it on Pricing for the option cards). Classes are prefixed nt-, pr- and foot-min
   so nothing leaks into the engine pages. Same tokens as nt-skin.css: Ember for the action, Ink
