/* BIANG — maison de haute disponibilité — and lucalivolsi.eu, set like magazine covers. The mastheads are Bodoni Moda (a
   high-contrast Didone, OFL) at a large optical size, letters tight, ".eu" small in the italic and tilted against the last
   letter, turned into SVG outlines by tools/wordmark.py. The cover picture is cover.webp over arcade.svg (tools/arcade.py: a
   Renaissance gallery with server racks in its bays); lucalivolsi.eu shows the drawing only. Fonts are served by this site
   only (the CSP allows nothing else): Bodoni Moda (tools/fonts/OFL.txt) subset by tools/webfonts.py, and Latin Modern Mono
   renamed "Biang Mono" for the colophon (GUST Font License, site/GUST-FONT-LICENSE.txt). */
