/* ── T19: VERTICAL SPINE + EVENTS ────────────────────────────────────────────
   Layout strategy:
   - .tl-spine (<ol>) is a vertical flex column — just stacks the <li> items.
   - Each .tl-event (<li>) is a flex ROW: date | node | content.
     In RTL, flex row starts from logical-start = visual right.
     This naturally places the date column on visual right (logical-start).
   - The spine line is drawn on .tl-spine via ::before, absolutely positioned
     to run through the center of the node column across all events.

   Node column center (for the ::before line):
     date column width (88px) + half of node column width (12px) = 100px
     But in RTL, inset-inline-start = distance from visual right edge.
     Container padding-inline = var(--ts-space-8) on wide screens.
     We use padding on .tl-spine to set a known left margin.

   Simpler approach: position the spine line relative to .tl-spine at
     inset-inline-start: calc(--ts-spine-col-date + center-of-node-col)
   Since .tl-spine has no padding itself, this is exact.
