/*
  SV Vorschlagsbox – ein System für beide Seiten (Einreichung und Moderation).

  Grundlage: Notion DESIGN.md aus voltagent/awesome-design-md – warme Neutraltöne, 1px-Haarlinien,
  8px-Controls, 12px-Karten, pastellfarbene "Property"-Tags für Kategorien. Notions violetter
  Primärton ist nach der Taste-Skill-Regel ("never violet") auf Notions eigenes Link-Blau gedreht.
  Schrift: Funnel Display / Funnel Sans (vom Taste-Skill für "software" gedealt).
  Bewegung: der Micro-Interaction-Layer des Taste-Skills (assets/motion), plus kleine,
  ReactBits-inspirierte Teile in app.js (CountUp, AnimatedList, ClickSpark).
