/* ============================================================
   W2G GUEST HOME — "The Team Board" (fable5 guest home redesign)
   ------------------------------------------------------------
   Loaded only by Prototype.html (after style-mobile.css).
   Every selector is scoped under `body.app-shell-guest #home`,
   so the authenticated app shell (body.app-shell-v2), the guest
   discovery views (#competitions/#teams/#members), Organizer,
   Admin, and Mission Center are structurally unreachable from
   this file.

   Why a dedicated file: the previous guest-home styles live in
   the 1.35 MB style-polish-v3.css override layer keyed to the
   old .guest-landing-handoff class names (now unused, therefore
   inert). Keeping the new surface in its own small file makes
   the redesign reviewable and instantly rollback-able (remove
   one <link> + this file).

   Colors, radii, and shadows come from the shared --w2g-* tokens
   defined in style-polish-v3.css for light and dark; no token is
   redefined here.
