/* ---------- the manifesto (Lucien, 2026-10-26): 学的是世界，会的是英语。 ----------
   Anime-film-title style (his choice): two poster lines, all one size, the last word of each line a touch bigger.
   Bold serif, white with a thin purple outline and a soft glow; the keywords warm to gold at the foot, with a twinkling sparkle.
   On load the first keyword flips through a few topics and settles on "world", then line 2 rises. */
