   HERO STORY STAGE — one deal auto-plays as a 5-act loop.
   Every animated part shares the SAME 18s duration; each act is carved out
   by keyframe percentages so the whole scene stays in lock-step.
     ① 入室・開始   0.0–2.5s    →   0–14%
     ② 会話（停滞） 2.5–6.0s    →  14–32%
     ③ 異変         6.0–9.0s    →  32–50%
     ④ 支援受信     8.6–11.9s   →  48–66%
     ⑤ 再開・改善  11.5–18.0s   →  64–100%

   The clock was 16s. Acts ①–④ keep their ABSOLUTE seconds (percentages simply
   rescaled ×16/18), so their felt tempo is unchanged; the whole +2s went to
   act ⑤, which grew 3.5s → 6.5s. That buys each of its three beats a hold
   long enough to actually read:
     自社「近い規模の…」    12.0–14.1s (2.1s)   67–78%
     先方「ぜひ伺いたいです」 14.3–16.5s (2.2s)   79–92%
     改善傾向ピル           14.9–17.9s (3.1s)   82.5–99.5%
   The pill is the story's conclusion — what the support actually achieved —
   so it holds longest of any beat. Every element is back to opacity 0 by
   100%: the loop must restart on an empty room, so don't let a beat run to
   the edge when retiming.

   The script is a causal chain, not four unrelated beats:
     ② 先方が費用対効果の懸念を出す → 担当者は機能説明に逃げる（弱い返し）
     ③ 会話が止まる（沈黙 8→12→18秒）→ 要注意
     ④ マネージャーが②で*やっていない*具体策を送る（同規模の導入事例）
     ⑤ 担当者がそれを実行 → 先方が前のめりに戻る → 改善傾向
   Act ④ must never restate what the rep already said in ②, or the support
   reads as worthless. Act ⑤ carries two bubbles so the recovery is *spoken*.
