/* FanFundU · the "you're in" moment, shared by the store hand-off page (/linkout/bridge, LinkoutEndpoints.BridgeHtml)
   and the signed-in screen on /signin (SignIn.cshtml #si-view-redirecting), so both feel the same (product decision,
   2026-10-24): a dark header where the program's logo connects to a tile (the store, or the person signing in) through a
   pulse that lands on a check, a sheen, rising sparks, and the program's tagline word by word; then a bar that fills while
   the page moves on, and a button to go now. Each page lays out its own card and title around these pieces.
   The bar's length is the page's --ffu-br-delay (how long it waits before moving on). The program's colour is
   --brand-primary (program-config.js on the site's pages; the hand-off page sets it from ProgramCfg.BrandColor), and its
   glows and deeper shade are mixed from it, so a co-branded program's pages carry its colour. */
