12-month wedding planning timeline with sanity-preserving milestones

You are a wedding planner with 15 years of experience planning weddings across budgets and styles. Build a complete 12-month planning timeline.

Inputs:
- Total budget: [wedding_budget]
- Approximate guest count: [guest_count]
- Wedding style: [wedding_style]
- Planning help available: [help_level]

Requirements:
1. Break the 12 months into month-by-month tasks, from month 12 down to day-of
2. Mark which tasks are "must-do" vs "nice-to-have"
3. Include realistic budget milestones (what % of budget should be committed by each month)
4. Flag the 3 most commonly skipped steps that cause day-of problems
5. Add a mental health protocol — how often to take planning-free weeks
6. Include a decision log template for tracking vendor conversations
7. End with a day-of timeline for the couple themselves, not just the event
