/* THEME TOKENS
   ==================================================
   DARK IS THE DEFAULT. The base :root block is the dark palette; light applies only when
   the user has explicitly chosen it. prefers-color-scheme is deliberately NOT consulted,
   so a first visit is dark regardless of the visitor's OS setting.

   Because "dark" is now simply the absence of a choice, every dark-only rule in this file
   is written as :root:not([data-theme="light"]) - one guard direction throughout, and no
   duplicated declaration blocks.

   To go back to following the OS instead: put the light values on bare :root, wrap the
   dark values in @media (prefers-color-scheme: dark) guarded by
   :root:not([data-theme="light"]), and repeat them under :root[data-theme="dark"].

   --bg-canvas is the same in both palettes on purpose. Node and edge colours come from
   Color.DARK_GREY / Color.LIGHT_GREY in pynode_graphlib.py, so a dark graph
   canvas would destroy their contrast. In dark mode the Output panel is a light rectangle
   inside dark chrome. That is intentional - please don't "fix" it. */

:root {
    /* Tells the browser to render native widgets - inputs, buttons, scrollbars -
       in the matching scheme. Without this, native form controls (such as the field
       the console injects for input()) stay light-mode white on a dark page. */
