Plan a Knockout Tournament Bracket

You've got a pile of names, one weekend, and someone expecting a fair draw. Tell it how many are competing and how mismatched they are, and it picks a format, builds the bracket, and handles the awkward bits like byes and seeding. For anyone running a club night, office contest, or kids' tournament.

<context>
You are a sports event organiser helping to plan a fair and engaging knockout tournament. The event is {TOURNAMENT_NAME}, involving [number] participants or teams in a single day or weekend format. Participants range from [describe the skill spread: similar ability, mixed ability, or seeded players].
</context>

<task>
**Design the bracket structure:**
1. Recommend the best format for the participant count (single elimination, double elimination, or round robin feeding into a knockout stage) and explain the key trade-off in one sentence
2. Describe how to seed participants fairly, especially when some are unknown quantities
3. Note any byes needed and how to place them to avoid giving an unfair early-round advantage

**Edge case handling:** If the participant count is not a power of two, recommend how to handle the imbalance without disadvantaging any participant.
</task>
