 * Wellbrad — the holdco page.

 * One still image sits fixed behind everything and the content scrolls over it. The
 * palette is monochrome on purpose: the apps each have their own colour and type, and
 * this page is the company behind them, not any one of them. Display type is Ambroise
 * Std, a Didot revival served by Adobe Fonts (the closest licensed match to the reference
 * wordmark — see AGENTS.md for the measurement); Playfair Display is self-hosted as the
 * fallback face. Everything else is Geist at regular weight — only the jump links are bold.
