A Nuxt layer holding overview, measurements, demographics, users, email
templates, feedback, discounts and AI usage, drawn on the WhileSmart
design system. Each destination owns a colour that carries its
navigation row, its icon and its page accents.

A host configures the API prefix, navigation, brand, skin, user columns
and chart drill-downs, and supplies the signed-in person through shared
state. Strings are written as their English text, so a host without a
translation layer renders them unchanged.
