Three features requested by Andrew Freiberg (physical-game player) and
refined by Seth, bringing digital blind chess closer to the physical
table:
1. Moderator announces every move and attempted move to both players
(widen announcement audience to 'both'; suppress bot retry churn).
2. Running capture tally (server-derived per-viewer protocol field).
3. Phantom opponent pieces — a client-local, drag-and-drop opponent-model
overlay, blind mode only, never sent to the server.
Spec only; no implementation. Phased: F1+F2 then F3.
