/* =====================================================================
   STYLE.CSS — how the whole website looks
   ---------------------------------------------------------------------
   Every page uses this one file, so a change here changes every page.

   QUICK GUIDE
   - Want to change a colour everywhere?  Edit the COLOURS list just
     below (section 1). Colours are written as "hex codes" like #A3482A.
     You can find hex codes for any colour by searching "colour picker".
   - Want to change the fonts?  See section 2.
   - The rest of the file is grouped by part of the page (navigation,
     hero, calendar, talks...). Each group has a heading like this one.

   A tiny bit of CSS vocabulary:
     .something { ... }   styles anything with class="something"
     padding               space INSIDE a box
     margin                space OUTSIDE a box
     gap                   space BETWEEN the items inside a box
     @media (...)          rules that only apply on small screens
