/*
  LC Toolkit design system, shared by every tool.

  Tokens first, so light and dark are the same rules with different values. Palette from
  the JSolve logo (navy, sky, leaf). A tool's own style.css only holds what is specific to
  that tool and uses these tokens.

  Short token names (--bg, --card, --text, --muted, --border, --accent ...) are kept as
  aliases because tool stylesheets use them.
