   Extras for the Timeline lens only (root class .tlv). Colours come from tokens.css; the quarter scrubber is the
   presentation's .tl component from site.css, tuned here. The head, the brief and the folded blocks (lk-*) are the shared kit;
   the chart, its controls and the side panel sit in the first block, open. */
