/* Ozon Bonus Hunter — feed-страница: filter UI + product grid.
 * Совместим с двумя проектами:
 *   - bot_Ozon: загружается ПОСЛЕ ozon-shell.css (тот переопределяет токены)
 *   - bot_Bonus: загружается одиночно (этот файл сам всё определяет)
 *
 * Layout v3 (2026-05-13): фильтры в боковом sidebar (а не inline в main).
 * Совместимость: классы .filters / .search / .cs / .slider-block / .histogram
 * / .dual-range / .grid / .card сохраняют семантику для legacy-кода.

 * Решение: histogram использует grid layout с N равными колонками, каждый

 * ширина). Track слайдера тоже инсетим симметрично: каждый край = column/2.
 *
 * JS устанавливает CSS-var `--hist-n` = количество бинов на .slider-block.
 * Тогда:
 *   - histogram: grid-template-columns: repeat(var(--hist-n), 1fr)
 *   - track inset: calc(50% / var(--hist-n))
 * И bar i центр = (i + 0.5) * (100% / N) = thumb position для value i.
