Start from Taxonomy and format
Modality, category, format, and season period need to start on the championship record.
In championship setup, the organizer defines modality, gender, category, Taxonomy and format, season dates, and the initial structure before opening the competition to teams and rounds.
That championship record becomes the reference for Matches, Table, Bracket, Scorers, Teams, and the Management tab instead of rebuilding the season in parallel spreadsheets.
