Stages (Swiss, round robin and knockout chained in any order, with cuts
staff confirm), the arbiter console (results, forfeits, pause and resume,
disputes, fair-play flags, forbidden pairs), registration forms and the
check-in desk, prizes and categories, teams and inter-club events built
from clubs, and exports (.xlsx, CSV, posters).

Presentation: sponsors as a shared library, per-event media, banners, ad
slots, sign-up links and codes, and a venue screen; the public live pages
show sponsors and a call to sign up. Clubs get a dashboard and a bulk
import of 20 clubs with their codes.

Club chat stays in step with membership: adding, removing or approving a
member here asks the player app to re-seat them (core/CommsSync.php), and a
club can make its chat announcements-only. Uploads are capped at 6 MB.
The game's look stays locked; nothing here restyles the manager.

Verified with tools/verify-{arbiter,teams,presentation,registrations,
stages}.mjs against a rehearsal of the player app.
