/*
 * TWO-COLUMN CONTENT + SIDEBAR GRID
 *
 * CRITICAL RULES — do not change without understanding why:
 *
 * 1. align-items: start on the grid container is MANDATORY for sticky sidebar.
 *    If omitted, the grid stretches rows to full height and the sidebar column
 *    becomes as tall as the content column — sticky has nothing to scroll
 *    against, so the sidebar drifts off-screen on long posts leaving a void.
 *
 * 2. minmax(0, 1fr) on the content column is MANDATORY to prevent overflow.
 *    Plain "1fr" can exceed its column when children (images, pre blocks) are
 *    wider than available space. minmax(0, 1fr) caps it at the grid boundary.
 *
 * 3. The sidebar uses align-self: start as a belt-and-braces guard on the
 *    element itself (in case the grid container rule is ever overridden).
