/* ============================================================
   JMK Contracting, concept homepage.
   Design read: local general contractor / renovation business,
   Durban KZN, trust-first audience (property admins, hospitals,
   schools, commercial, private homes). Structural, daylight,
   credibility-driven language, not a SaaS or tourism aesthetic.
   Vanilla HTML/CSS/JS, no build step.
   Dials: variance 6, motion 4, density 4. One accent (JMK's real
   brand green), one radius family (6px controls, 10px cards, pill
   only for small tags), light theme locked across every section.
   This is a concept pitch, not the live site, see footer notice.
