/* Portfolio, dark "grid" version (spec: portfolio-design-tokens.md, 2026-11-04).
 *
 * Desktop: the content is a 12-column grid of square cells. The design is drawn
 * at 1440px (120px cells); everything is sized in --px, one design pixel. The
 * scale is the smaller of "12 cells fill the width" and "the 8-row hero fills
 * the viewport height", so the hero (and its Contact button) always fits on
 * screen. When the height wins, the content stays centered and the background
 * grid keeps going to the left and right, aligned with the content's cells.
 * Phones (< 900px): a 4-column grid; blocks stack and snap to whole cells
 * (main.js sets --rows on [data-snap] blocks whose height depends on text).
