/* =====================================================================
   DETOKO — styles.css
   A house of small Australian brands.

   Design system overview
   ----------------------
   Concept ...... Detoko is the calm "frame" that holds colourful brands.
                  The deep-eucalypt surface recurs (hero, values, footer)
                  as that frame; oat-paper sections sit between it.
   Type ......... Bricolage Grotesque (display) · Hanken Grotesk (body)
                  · Spline Sans Mono (utility labels)
   Accent ....... a single ochre jewel — used sparingly, never as filler.
