Seeded, byes placed, ready to print.

Thirteen players, so a 16 bracket with three byes, and the byes must go to the top seeds, and seed 1 must be on the opposite side from seed 2, and in double elimination the losers of round two must not immediately replay the people they just lost to. This is the part that goes wrong at 8 am on tournament day. This does it in a second.

WHAT IT DOES

• Standard seeding: 1 v 16, 8 v 9, 4 v 13, 5 v 12 and so on, so the top seeds meet last
• Byes to the top seeds, auto-advanced
• Single elimination, with an optional third-place match
• Double elimination: full losers bracket with the standard drop pattern (losers enter in reverse order to avoid rematches) and a grand final
• Click a name to record the winner; everything downstream fills in, the loser drops, undo by clicking again
• Match IDs on every box so the desk can call "L3-2 to court 4"
• Scores: record 6-3 6-4 or 2-1 on each match; they print with the bracket
• Schedule: courts, first match time, minutes per match and rest between. Every match is placed on the first free court once both feeder matches have finished, so nobody plays twice in a row, and you get the time the day ends
• Print layout; backup export
