/* Plöhnen Software — one-page site.
   Colours are taken from the logo itself: near-black #0a0b0c ground
   (the wordmark is white, so the page must stay dark), screen blue
   #34b9fa accent, monitor-frame grey #4d4d4d. Graphics are SVG only.
   Type is Maple Mono, same variable woff2 pair (normal + italic,
   weight 100–900) the portfolio loads via next/font/local from its
   maple-font submodule (v8.0-beta.2); vendored here under fonts/
   with its OFL.txt, since a static site has no build step. */
