/* Integra Technical Services: the site shell and the platform's fixes.

   integra-homepage.css is Sophia's page design, copied UNTOUCHED from her
   export by scripts/convert_integra_site.py, so a fresh export can be dropped
   over it. Everything the platform adds lives here instead: the header and
   its full-screen phone menu, the footer, the phone action bar, the real
   enquiry form, and the client's own design fix (no decorative dash before a
   section's small line). */
