/* ================================================================
   AlpineFlow — Default Theme (Light + Dark)

   A neutral, professional theme using the zinc gray scale with a
   slate accent. Designed to fit most applications out of the box.
   Change --flow-node-selected-border-color (and its related accent
   variables) to quickly brand the flow to your app's primary color.

   Supports class-based dark mode (same convention as Tailwind v4):
     - Light by default
     - Dark when .dark is on an ancestor or .flow-container itself
     - System preference is handled by the host framework (e.g. Flux)
       toggling the .dark class based on prefers-color-scheme

   Override any --flow-* variable on .flow-container to customise.
