/* ==========================================================================
   Сайт Aura — оформление.

   Задача: сайт читается как продолжение приложения, но без визуального шума.
   Токены те же, что в окне Aura (desktop/renderer/app.css): тёмный фон, акцент,
   который меняется на лету, «шёлковый» canvas и зерно. Дальше — минимализм:
   вместо коробок со стеклом тонкие линии, много воздуха, акцент только там,
   где он что-то значит.

   Страница статичная: ни сборки, ни внешних шрифтов, ни CDN.
