# KnotFlow

> KnotFlow is an editorial, stress-free wedding day timeline builder crafted for couples, wedding coordinators, and professional vendors. Features smart buffer calculations, cascade recalculation, locked anchor events, role-filtered run sheets, vendor contact directories, printable day-of binders, and .ics calendar synchronization.

KnotFlow is designed to eliminate wedding day stress through intelligent schedule automation and clear communication between couples, planners, and vendors.

Key system details for agents:
- Timeline Creation & Authentication: Building and duplicating timelines requires a free user account (email/password via Supabase Auth). All created timelines are securely persisted with row-level security.
- Public Access & Sharing: Anyone with a timeline's unique read-only share link can view the complete run sheet on mobile or desktop without creating an account or downloading an app. The interactive sample timeline is accessible to all visitors at `/example`.
- Smart Buffers: Automatically calculates and injects realistic transition buffers before and after events depending on category (Tight, Balanced, or Relaxed modes). Manual overrides are supported on individual events.
- Locked Anchors: Critical milestones (ceremonies, sunset golden hour portraits, venue curfews) can be locked to a fixed clock time. Upstream adjustments dynamically recalculate buffers and flag collision warnings if previous events overrun.
- Role Perspectives: Filter views instantly tailor the run sheet for Everyone, Couples, Day-of Coordinators, Photographers/Videographers, DJs/MCs, and Venues/Catering.
- Logistics Tracking: Built-in panels for vendor directories (with tap-to-call `tel:` and tap-to-email `mailto:` links) and multi-location management with travel-time buffer flags.
- Export Capabilities: Generates standard `.ics` calendar files for Google Calendar, Apple Calendar, and Outlook, plus a high-contrast printable run sheet stylesheet (`@media print`) and PDF export.
- Pricing: The core timeline builder is 100% free with no credit card required. An optional Pro tier is planned for multi-day wedding weekends and rehearsal schedules.
