/* Studentix — окно «План работы» (docs/PLAN-WINDOW.md §3, docs/DESIGN.md «Дизайн-язык проекта», «Стеклянный стиль», «Редактор: стиль и контролы»).
   Классы с префиксом .stx-plan__, разметку строит js/plan.js. Режимы — атрибут data-mode: desktop / tablet / phone.
   S31-r (2026-10-01): светлая тема по умолчанию, тёмная — только через <html data-theme="dark"> в tokens.css.
   Цвета, радиусы, тени и стекло — только из css/tokens.css (--stx-*). Переменные --p-* — алиасы с запасными
   значениями из палитры tokens.css, чтобы окно не разваливалось без tokens.css.
   Стекло — только у плавающих частей: правая панель, нижняя полоса. Список плана — плоское белое.
   Селекты (.stx-select*), тумблеры (.stx-switch*), кнопки — вид из tokens.css; здесь только размеры и расположение. */
