 *
 * Connector line positioning math — must stay in sync with --timeline-avatar-size:
 *
 *   --timeline-line-x: card padding + half the avatar width
 *     → centers the vertical connector line on the avatar column
 *
 *   --timeline-line-center-y: card padding + avatar top offset + half avatar height

 *
 * If you change --timeline-avatar-size, the line and dot will shift automatically
