One landing page, Advantage Plus, that renders feeds from Prime, Partnerhub, FXLink, PCT and Tradewinds. Role-aware: advisors see all five tools and their actions; investors see Prime, Partnerhub, FXLink and Tradewinds with their own items. Calm, editorial density. Four design systems, each lightly themeable per partner.

Each partner supplies a primary, a secondary, a logo and (optionally) background imagery. Everything else is fixed per system. Colours flow through four CSS variables: --p primary, --s secondary, --p-ink primary darkened for text on light paper, --p-soft primary tinted for washes. Maps 1:1 to Tailwind 4 @theme tokens.

Every app emits the same six item shapes: document ready, article, action required, figure, event, status. Each system renders those six shapes in its own voice, so a new app plugs in without new design work.

Different macrostructure, nav and footer per system (Workbench, Photographic dark and light, Technical-editorial grid). Horizon background imagery is shared across partners unless a partner supplies its own. Character-matrix imagery in Register is generated typography, not SVG. Roman headings only, no gradients, no icon-tile cards, no fabricated marketing stats. Partnerhub items are the live RSS feed; other values are sample data and are labelled as such.
