/**
 * Variant CSS: history--milestone-timeline
 *
 * Company history as a vertical timeline. Each node = a big year on the left and a
 * milestone title + one line on the right, threaded onto a single connector line
 * with accent dots. The final "Dziś" node gets a filled dot to read as the present.
 * Text stays --ink (polarity-aware); year, dots and the em take --accent. The track
 * collapses to a tighter left rail on mobile, no horizontal overflow. First variant
 * of the new `history` role.
