Universe definition
Candidate-player pool. Anyone who has been called up to a senior national team for a WC2026-qualified nation in the last 24 months. This is a superset of the eventual 26-man squads (released ~June 2026) and lets us pre-build features before final squad announcements. Rough size: 48 nations × ~50 candidates ≈ 2,400 players.
Out of scope. U-21/U-23 selections (unless a player has also been in a senior call-up); youth-academy players; players uncapped at senior level; retired internationals.
