  "summary": "Add realistic buffer time to a wedding timeline so vendors and photos don't run late.",
  "description": "Wedding timelines built from vendor-quoted durations without buffer almost always run late, because getting-ready delays, photo transitions, and guest movement between locations eat time that no single vendor's estimate accounts for. This calculator takes the sum of your scheduled block durations and applies buffer percentages by block type — hair/makeup and family formals need the most padding, ceremony and toasts need the least — to output a realistic total day length and a suggested vendor end time.",
  "formula": "Buffered time = scheduled time × (1 + buffer %); total day length = Σ buffered blocks + transition time.",

  "faq": [
    {
      "q": "Why does the photo block need the most buffer?",
      "a": "Family formals routinely run long because family members wander off, group combinations take longer to organize than planned, and golden-hour couple portraits get squeezed by every delay earlier in the day. A 25%-30% buffer on this block is standard advice from wedding planners and photographers alike."
    },
    {
      "q": "How much time should I budget for transitions between locations?",
      "a": "Plan roughly 20 minutes per move for guest transportation and vendor re-setup, more if it involves a shuttle or a drive over 10 minutes. This is time that doesn't show up in any single vendor's quoted hours but absolutely appears on the day."
    },
    {
      "q": "Does hair and makeup really need 20% buffer?",
      "a": "Yes — an extra bridesmaid deciding on a touch-up, a late arrival, or a hairstyle redo are common, and this block sets the anchor time for everything after it. Padding it protects the rest of the day from a cascading delay."
    },
    {
      "q": "Should the buffered total match what I tell vendors?",
      "a": "Use the buffered total for your own planning and for setting hard stop times with your photographer/videographer end time, but keep individual vendor call times based on the unbuffered schedule so they arrive precisely when needed rather than early."
