   One file, organised in numbered sections. Search for "== N." to jump.

   1.  Fonts
   2.  Design tokens (colours, spacing, radii…)  <- change brand values here
   3.  Base / reset / typography
   4.  Layout helpers (container, section, stack, grids)
   5.  Reusable components (buttons, chips, cards, links…)
   6.  Site header & navigation
   7.  Home: hero
   8.  Home: news ticker
   9.  Home: mission + photo strip
   10. Home: solutions (tabs and panels)
   11. Home: contact / inquiry form
   12. Home: careers teaser + investors
   13. Site footer
   14. Careers page
   15. Utilities, reveal-on-scroll, reduced motion

   Naming: BEM-style – .block, .block__element, .block--modifier.
   State classes always start with "is-" (is-open, is-active, is-on…).
