/* ---------------------------------------------------------------------------
   人事风暴 — UI visual language, derived from the game's own art direction:
   an HR dossier on a desk at night. Paper stock (the same paper.webp that
   dresses the desk), ink-grey rules, one vermilion accent = the company seal,
   teal = data. Panels are documents: warm paper ground, a double hairline
   rule at the edge instead of a border-radius card, a filing tab at the top,
   and motion that settles like a sheet being laid down rather than fading in.
   Typeface class: a serif for headings and story (Songti / Georgia — the
   register of a printed personnel file), a humanist sans for data readouts.
