/* Theme contract
   --------------
   A theme supplies the light and dark palette inputs below. The scheme block
   selects one palette, semantic roles derive from it, and components consume
   only semantic/component roles. This keeps alternate themes small and lets a
   caller override one component role on any subtree without forking its CSS.

   Public selectors:
     data-theme="matrix" | "workbench" | "workbench-inverse" | "screen" |
       "mineral" (matrix is the default)
     data-color-scheme="light" | "dark" (unset follows the OS)

   Public override examples:
     --color-accent: rebeccapurple;
     --color-scrollbar: #aaa;
     --prompt-bg: var(--color-surface-raised);
     --rail-bg: canvas;

   This file is the house contract: the tokens the workbench and portal apps
   share verbatim. `frontend/workbench/src/styles/tokens.css` layers the
   workbench-private component roles and shell geometry on top of it; it
   redefines nothing here. A portal app loads this file alone.

/* House primitives

   The small primitive vocabulary a portal app gets for free. It consumes only

   plain <link> and `.house-*` classes with data-attribute states.

   Every block below mirrors a rule the workbench already ships, and says
   which. When the two disagree the workbench is right; fix this file rather
   than diverging. Geometry lives in the token block immediately below — rule
   bodies never restate a px value, exactly as the spacing ladder demands.

   The laws these encode (frontend/workbench/docs/DESIGN.md): quiet chrome;
   two-audience failures; no anonymous spinner; one UI face; tokens own
   geometry; selection is a ground; there is no card primitive.
