/**
 * Variant CSS: process--sticky-side-steps
 *
 * A left heading column that pins (position:sticky) while a right numbered steps
 * list scrolls past it. The right list is open (no card/panel framing): a thin
 * vertical guide rail runs behind large display numbers, with hairline row
 * separators between steps. The sticky aside + open numbered list set it apart
 * from checklist-panel (framed bordered card + small badge rows), the timeline
 * and the full-width step rows. Numbers + em take --accent; titles stay --ink
 * (polarity-aware), descriptions muted. Columns stack on mobile and the sticky
 * behaviour is dropped. Part of the `process` role. Every selector scoped.
