 * Not a green WhatsApp clone. Deep-black canvas, glass panels, gold hairlines, periwinkle focus.
 * WhatsApp green is spent ONLY on the "live/connected" affordance — that restraint is the whole
 * difference between elite and clone. Palette is the CRM's measured brand: gold #d4af37,
 * periwinkle #5b8def, canvas #0c1019 / paper #141a26, green #25D366 for live only.
