/*
  Product detail — shared by the 10 szerelvenygyartas.html product-card
  subpages (code/szerelvenygyartas/, filenames slugified from their full
  product title, e.g.
  "fojtokupos_szabalyozo_illetve_elzaro_szelepek_200c_ig_020_as_tipus.html")
  and the 6 leser-termekek.html product-card subpages (code/leser-termekek/).
  Each page reuses page-hero.css for its header; this file covers the
  blocks unique to these pages: a spec sheet (label/value pairs, only the
  rows that particular product actually has on the real brunnbauer.hu
  page), an optional .product-detail__family sub-group (a repeated
  heading + spec grid used when one product page covers several distinct
  sub-families, e.g. the LESER rugóterhelésű/vezérelt pages' six/two
  families), and a rehosted-PDF downloads list. The 126/166
  szerelvenygyartas pages and most leser-termekek pages add a
  .product-detail__advantages bullet list; the 016 szerelvenygyartas page
  and two leser-termekek pages (biztonsági szelep átadása, leser
  raktárkészlet) have no .product-detail__downloads block — no PDFs exist
  for those on the old site.
