/*
 * Desktop layout — CSS Grid trick:
 *   column 1 = 0px  → sidebar lives here but is translated LEFT
 *                      so it appears outside the content container
 *   column 2 = 1fr  → .dtoc-body keeps its FULL original width
 *
 * Requires ~244px of free space to the left of the content block.
 * Works on most themes at ≥ 992px when content has a centred max-width.
