/* ==========================================================================
   HealthCentre.Ai — design system
   Recoloured to the TEMPLESPA palette: deep petrol teal (#11555D) as the
   signature brand colour, a refined champagne gold accent, on clean cool
   near-white / light teal-grey surfaces with neutral charcoal text. Warm
   optical serif display (Fraunces) + Switzer UI + Geist Mono labels.
   Token NAMES kept (--forest/--pine/--amber...) so all rules stay wired;
   only their VALUES changed. Green hue 152 → teal hue ~207; amber → gold.
