   MatrixLine Cloud — design tokens
   Every colour, size and timing the panel uses, in one place. Loaded by
   partials/head.php before app.css, so the stylesheets after it (and pages
   that load only this file) read the same values.

   :root                                       scale: type, durations, easing
   html[data-skin="black"]                     the dark theme (default)
   html[data-skin="black"][data-theme="light"] the light theme

   Token names are shared with app.css, which keeps light base values for
   the unskinned invoice print page. Component rules live in app.css,
   skin.css and design.css; this file only declares values.
