   style.css — оформление анализатора русских шашек
   ───────────────────────────────────────────────────────────────────
   Оглавление секций:
     1. Токены темы (:root / [data-theme])      — цвета интерфейса
     2. База и шапка                              — сброс, topbar, бренд, меню
     3. Сетка приложения                          — .app, board-zone, side-panel
     4. Плашки игроков                            — индикатор хода/результата
     5. Доска и координаты                        — .board-frame, .board, .coords
     6. Клетки и фигуры                           — .square, .piece (читают скин)
     7. Подсветки                                 — ход, выбор, подсказки
     8. Панель навигации                          — .controls, .ctrl-btn
     9. Панели и нотация                          — .panel, .movelist, дерево
    10. Расстановка позиции                       — тулбар, FEN-плашка, паспорт
    11. Формы и модалки                           — поля, модалки, тост
    12. Пикеры темы и скина                       — дропдауны со свотчами
    13. Палитры тем                               — [data-theme="…"]
    14. Скины доски и фигур                       — [data-board="…"]
    15. Анимации, утилиты, адаптив
   ───────────────────────────────────────────────────────────────────
   Два независимых слоя оформления:
     • [data-theme] красит ИНТЕРФЕЙС (фон, панели, текст, акцент);
     • [data-board] красит ДОСКУ И ФИГУРЫ через дизайн-переменные
       (--piece-*, --sq-*-bg, --frame-bg, --king-*). Слои ортогональны:
       любой скин доски корректно выглядит на любой теме.
   Контраст чёрных фигур на тёмных полях (фигуры стоят только там)
   обеспечен светлым ореолом в box-shadow + усиленным верхним бликом.
