 * Dark theme only, tokens extracted from datacenter-1.ru, Oswald headings and Inter text (self-hosted, assets/fonts/).
 * Plain CSS, no build step. Layout rules: no fixed widths, no nowrap, flex/grid children get min-width: 0, rows wrap.

   size-adjust is the measured width ratio of the Russian sample text, the overrides come from the font's hhea metrics. */
