/*
  Style sheet for the CLS CastLab Supply website.

  The design palette and layout are inspired by the official
  Ransom & Randolph website, using a vibrant orange as the
  primary accent color alongside deep charcoal backgrounds and
  clean white surfaces. The font family Montserrat provides a
  modern, industrial feel while remaining highly readable.

  Theme tokens

  IMPORTANT: The light theme is the styling reference. Dark mode should keep the
  same layout, typography, spacing and component styling — only colors change.
  To achieve that, most colors below are expressed as tokens and the dark theme
  overrides only those tokens.
