/* ==========================================================================
   Spadel + DEVIN Purpose Book — Bulgarian (Cyrillic) web edition
   ==========================================================================
   Typography: headings in Lora, a Cyrillic-capable serif chosen as the
   closest match to the original book's Fraunces (which has no Cyrillic);
   body and UI text in Noto Sans, the family devin-bg.com uses. Heading
   sizes follow the original PDF, which sets display type large and loose.
   Brand names are rendered as the real Spadel / DEVIN logos (see
   "Brand logos" below), not typed text.
