/* promptdecode · promptdeco.de
   One stylesheet for one page. Tokens first, then layout, then components.
   Ported by hand from the Claude Design canvas `promptdecode.dc.html`, which
   held its styles inline; the token names are the canvas's own.

   Themes. Dark is the design's default, but the page follows the reader's
   system preference when they have not chosen, so that a light-mode visitor
   is not flashed a black page before the script runs. `data-theme` on <html>
   is an explicit choice by the toggle and always wins. The Content-Security-
   Policy forbids inline script, so there is no head snippet to set it earlier
   than this. */

/* Theme switching, and why there is no cross-fade.
   Chrome does not restart a transition when the end value comes from a custom
   property that changed on an ancestor: the element keeps painting the old
   colour, indefinitely, and the page half-changes theme. The design canvas
   transitioned the body's background and colour and hit exactly that. Since a
   theme flip moves every token at once, transitions are suppressed for the one
   frame it happens in, and the switch is instant. Hover and focus transitions
