/* ============================================================
   TOKENS — the whole design lives in this file.

   These names are the KIT TOKEN CONTRACT. Rename nothing;
   RE-VALUE everything. See DESIGN-LANGUAGE.md for the argument
   each value is making.

   The palette is the house palette from `btmz-brand`:

     Chop Red   #B4120A   the mark, and NOTHING else
     Stock      #F7F2EA   the paper the mark is pressed on
     Ink        #1A1614   text

   Those three are fixed brand values. Everything else here is a
   ramp derived from them so the sheet has depth without
   introducing a fourth hue.

   CHOP RED IS RESERVED. It is bound to --brand and --brand is
   painted on exactly one element: the mark. If you find yourself
   reaching for it for a button, a link or a rule, the answer is
   --ink. A signature that appears twice on a page stops being a
   signature and becomes decoration.

   STRUCTURAL WARNING — the APCA gate parses this file by selector
   block. Keep the three blocks exactly as they are (`:root`, then
   `:root, :root[data-theme="dark"]`, then `:root[data-theme="light"]`)
   or the gate will read an empty palette and silently pass nothing.
   ============================================================ */

     installed. The page is set in a grotesque for the same reason
     the launch screens are: a name set in Rockwell competes with
     the chop instead of sitting under it. */

/* The night shift. Keyed BY NAME — the gate finds the dark palette by
   [data-theme="dark"] and the light one by [data-theme="light"].

   The ground sits BELOW Ink rather than at it. A true #1A1614 ground
   would put the mark's own field at the same value as the page and the
   chop would stop reading as something pressed ONTO a surface. Dropping
   the ground is the same move splash.py makes for the dark launch
   screen, and for the same reason. */
