/* Physiome - B+R project page.
   Every value here is lifted from the original Elementor CSS (kit post-7, page post-2,
   header post-73, footer post-113) rather than eyeballed, so the rebuild matches 1:1.

   NOTE ON THE BODY FONT: the kit sets `font-family:"Nocturne Serif"` for body and h2, but
   the site only ever declares @font-face families 'Vilane' and 'Nocturne'. "Nocturne
   Serif" therefore matches nothing and falls through to the generic sans-serif. That is
   reproduced here deliberately so the rebuild renders identically. Aliasing it to the
   real Nocturne file is a one-line change if that bug should be fixed. */
