/* --- Navbar: current-page marker ------------------------------------
   The vendored css/bootstrap.min.css in each site folder was hand-themed years
   ago, and its .active rule was never updated to match:

       personal  color:#fff        on background:#E7D9C1   -> contrast 1.39:1
       AMEP Lab  color:#E7D9C1     on background:#E7D9C1   -> contrast 1.00:1

   Either way the current page's label is unreadable -- on the lab site it is
   literally the same color as the block behind it, so the nav looks like it has
   a blank gap in it. Do NOT fix this by editing bootstrap.min.css; it is a
   vendored file and every site convention here says shared styling lives in
   site.css. Override it instead.

   --nav-link is the bar's own link color and is the ONLY value that differs
   between the two copies of this stylesheet: crimson on the personal site
   (cream bar), white on the lab site (crimson bar). */
