/* ==========================================================================
   Chalkidiki Pearl - design system

   The site is organised like an architect's document set rather than a
   brochure: hairline rules, tabular figures, and a section drawing doing the
   work a hero photograph would normally do. The palette is taken from the
   renders themselves - chalk, graphite, and the green-blue of the Toroneos
   gulf - and the page commits to that single daylight world deliberately, so
   every colour below is stated outright rather than inherited from the host.
