/* Institute for The Study Of Humanity: house style for the association pages.
   Colours, type and sizes come from handoff-v14/mockup_v2 and yapper-research-mockup-v5.html.
   The bar's behaviour follows yapperphone.app's top bar (src/App.jsx, src/index.css); its content and colours are the Institute's.
   This file is identical in isoh-research and maximized-impact-site: edit both. */
