{event-budget}

Build the budget and P&L for a technical event - every cost line split into fixed and per-head, the revenue mix against the funding model, a Good/Better/Best scope-tier ladder so break-even has three answers instead of one, a contingency sized as a stacked floor, pad and downgrade ladder whose cuts also price lost sponsor reach, a cross-edition reserve policy, annual funding decoupled from single events, and outflows scheduled against the dates sponsor and ticket money actually lands. Use whenever asked to build an event budget, model conference or hackathon costs, find break-even, size a contingency reserve, set a reserve or surplus policy across editions, fund a recurring meetup series annually, plan event cash flow, or decide what to cut when revenue falls short. Consumes prices and real vendor quotes, never sets them. Do NOT use to set ticket or sponsor prices - use samber/dev-event-organizer-skills@event-ticket-pricing or samber/dev-event-organizer-skills@event-sponsor-pricing.
