/*
  Design: "Ermittlungsakte" — Bingo als Beweisprotokoll.
  Passend zum Heldendumm-Thema (Geschichte/True Crime), aber eigenständig
  vom taktischen HUD-Look der anderen Besiuk-Projekte: hier warmes
  Aktenpapier statt kaltes Radar-Display, weil das Bingo ein Spiel für
  die Hörerschaft ist, kein Operations-Tool.

  Farben:
    --paper:      #ece5d3   (vergilbtes Papier)
    --ink:        #221d17   (Fülltinte, fast schwarz)
    --stamp-red:  #9c2b1f   (Aktenstempel-Rot)
    --folder:     #b8a074   (Manila-Ordner-Beige)
    --verified:   #3c5e3a   (Bestätigt-Grün, gedeckt)
    --line:       #c9bd9e   (Trennlinien)

  Typo:
    Display: 'Special Elite' (Schreibmaschine) für Überschriften/Stempel
    Body: 'Source Serif 4' für Fließtext
    Data: 'JetBrains Mono' für Timestamps/Zahlen
  (alle self-hosted einbinden, siehe /assets/fonts/ — hier Systemfallback)
