/* ------------------------------------------------------------------------
   thri5.co.uk: Thri5 Project Consulting.

   Thri5 has its own identity, separate from the ThriveFSM brand system, so
   this page does not load shared/brand.css. It keeps the original Thri5
   "5" mark, redrawn as a vector and deepened to a mature teal, on a
   graphite and pale teal-grey palette.

   - Manrope 600 for display, Geist for body, Geist Mono for labels.
   - Dark graphite top and footer; the sections between them alternate two
     pale teal-grey bands, and the colour change is the divider.
   - Teal is an accent only: labels, numbers, links and one phrase.
   - Force light: explicit colours, painted as same-colour gradients, so a
     phone's forced dark mode cannot invert them.
   - No scripts of its own. Contrast is checked to WCAG AA for body text.
