   This block is already in place at the top of style.css.
   It matches the files exactly as downloaded from gwfh.mranftl.com
   (v20, latin). Expects these 7 files in /public_html/fonts/ :
     manrope-v20-latin-regular.woff2  (= weight 400)
     manrope-v20-latin-500.woff2
     manrope-v20-latin-600.woff2
     manrope-v20-latin-700.woff2
     inter-v20-latin-regular.woff2    (= weight 400)
     inter-v20-latin-500.woff2
     inter-v20-latin-600.woff2

   font-display: swap  → text shows immediately in the fallback
   font, then swaps to the real one when it loads.
   Absolute paths (/fonts/...) resolve from any page depth.
