   Each line prints on left-to-right (one-shot clip-path wipe in character-

   and a block caret blinks at the line end then extinguishes. Triggered by
   the per-li .is-in that reveal.js's [data-reveal-group] injects; the --d
   group stagger (i*80ms) is widened via calc for teletype pacing. The li
   opts out of the stock rise (the .finale .kicker pattern).

   Cascade notes: this selector (0,2,1) outranks [data-reveal].is-in
   (0,2,0), so the base opacity:0 would win even after reveal — the print
   keyframe therefore carries opacity:1 and holds it with `forwards`
   (animations beat all normal declarations). No-JS is safe two ways: the
