/* ==========================================================================
   Liittyvät artikkelit — "Dossier" v5.1 (korvaa "Harrasteblogi Related
   Posts" -lisäosan assets/css/style.css:n, sisältö käytännössä muuttamaton).
   Pääväri:   #d6111e (punainen)
   Aksentti:  #ddc76d (kulta / foliokorostus)

   Suunnitteluidea: ei tavanomainen "poster-kortti-ruudukko". Sen sijaan
   arkistomainen "dossier"-asettelu: ensimmäinen artikkeli nousee esiin
   leveänä kohokorttina, loput asettuvat tiiviiksi indeksilistaksi jossa
   jokaisella kortilla on oma haamunumero (01, 02, …) ja kultainen
   "leimattu" kulma — viittaus fyysiseen arkistokorttiin / pääsylippuun.

   Kaikki selektorit ovat omalla ".hb-related-wrapper"-nimiavaruudellaan,
   joten mitään uudelleenskoopausta ei tarvinnut tehdä sitä varten että
   site.css ladataan joka sivulla — tämä tyylitiedosto ladataan silti vain
   yksittäisen artikkelin sivuilla (ks. hb_core_related_enqueue_assets()).
