/* =========================================================
   ARAM MIZURI ARCHITECTURE — site-index.css
   The menu on every page: the Index button, Contact and the three
   languages in the bar, and the Index itself — the site as the index sheet
   of a set of drawings (partials/site-index): a frame drawn in, the sheets
   numbered A-00 to A-10 in a schedule, H-01 Kurdistan's architectural
   heritage with the landmark of the day, and a title block along the foot.
   Loaded by the homepage (style.css) and by every other page (project.css),
   so it carries its own colours rather than relying on either.
