/* ==========================================================================
   THINK NEXT — concept page design system
   --------------------------------------------------------------------------
   One vocabulary, three tiers of departure from the current thinkconsulting.com
   design. Put the tier class on every top-level section alongside `tk-section`:

     .tk-t-big     Boldest. Dark canvas, full-bleed, display type, ticker.
     .tk-t-med     Halfway. Light canvas, one dark band, display type, no ticker.
     .tk-t-small   Closest to today's site. Their serif headings, their square
                   blue buttons, white canvas, conventional rhythm.

   Palette is Think's own blue and charcoal — no secondary hues, no gradients on
   type. Every selector is namespaced `tk-*`, so this file is inert anywhere it
   is not deliberately used. Loaded on the front end AND in the block editor.
   ========================================================================== */

   faithfully (the theme only loads it on the front end). */
