   Dracon Draw — дизайн-система v2 (S5, 07.09.2026)
   Тёмная инженерная тема по умолчанию, светлая — по переключателю (html[data-theme]).
   ВСЕ параметры темы и акцентов — в блоке токенов ниже. Шрифты локальные, без CDN:
   Inter (текст), Unbounded (заголовки H1–H2 и крупные числа; S6, решение заказчика 07.09.2026),
   JetBrains Mono (подписи, числа, факты), osifont (графы основной надписи, ГОСТ 2.304).
   Лицензии — в /static/fonts/. Unbounded — переменная гарнитура 200–900 (SIL OFL 1.1),
   файлы woff2 по подмножествам скачаны с Google Fonts (fonts.gstatic.com/s/unbounded/v12/…),
   текст лицензии — из репозитория гарнитуры github.com/googlefonts/unbounded (OFL.txt).
