/* ============================================================================
   TIKTÓ — a temporal-spatial interface system for heavy money & infra products
   ----------------------------------------------------------------------------
   Reusable across products. Namespaced --tk-* so it never collides.
   Two themes: default (terminal-premium dark) and [data-tk-theme="light"]
   (institutional). Drop in <link rel="stylesheet" href="tikto.css"> and go.

   Design law (inherited from high-stakes UX: IEC 62366 / EEMUA 191 / Endsley /
   Tufte): restraint is a safety feature. One accent for "act here". Numbers are
   tabular. Motion is signal, never decoration. Fail loud, never silent.
