   KIEZLY — DESIGN TOKENS
   ============================================================================
   The entire visual identity lives in this file. A rebrand = editing tokens,
   never component CSS. Keep GROUP colors in sync with CONFIG.GROUP_COLORS
   in js/config.js (map markers are drawn from JS).

   Identity: dark navy + gold, inspired by Berlin U-Bahn signage — deep tunnel
   navy, warm platform-light gold, signage-style uppercase labels.

   Themes: default dark (U-Bahn tunnel). Light mode via [data-theme="light"].
