   Brandywine Technical Partners — Site Stylesheet
   --------------------------------------------------------------------------
   This file is organised top-to-bottom so you can find things quickly:

     1.  Design tokens (colours, spacing, type) ....... :root
     2.  Reset & base element styles
     3.  Layout helpers (.container, .grid, .split)
     4.  Buttons
     5.  Site header & navigation
     6.  Hero sections
     7.  Content sections & section headings
     8.  Cards (feature, product, tutorial, link)
     9.  Logo strips / customer logos
     10. Lists, pills, tables, accordions
     11. Media blocks (audio players, video embeds)
     12. Call-to-action bands
     13. Site footer
     14. Utilities
     15. Responsive breakpoints

   Tweaking tips
     • Almost every colour and size is a variable in section 1. Change it
       there once and it updates everywhere.
     • Nothing here is minified or auto-generated — edit freely.
     • There are no CSS frameworks and no build step. Just save and refresh.
