/* ---------- Design tokens ---------- */
/*
 * Two independent Customizer controls drive theming:
 *  - Colorway (body.rst-colorway-*): swaps --accent-dark/-light/-bright, everywhere.
 *  - Mode (body.rst-mode-dark): swaps surface/ink tokens for the sections that were
 *    "light" (story/stack/certs/journey/blog) between light-on-white and light-on-dark.
 * Hero/Lab/Contact are always dark regardless of mode, so they reference
 * --accent-dark/--text-dark-* directly rather than the mode-aware --ink-* aliases.
