/* --- Alfabet (headings) ---------------------------------------------------
   Alfabet is a commercial typeface (Machalski / Capitalics). Drop licensed
   .woff2 files into /assets/fonts/ and these rules pick them up. Until then
   headings fall back to Space Grotesk, which is metrically close enough that
   nothing reflows badly. Alternative: swap these @font-face blocks for an
   Adobe Fonts kit <link> in each page head.
