# Crussell

Nail salon booking platform — Go 1.25 backend + SvelteKit 5 frontend + Docker. Built for a UK sole-trader nail artist.

## Features

- **Three booking flows**: self-service (customer), walk-in (admin), call-in (admin)
- **Slot reservations**: temporary holds prevent double-booking (4 TTL types)
- **Guest accounts**: disposable accounts for one-off bookings, GDPR-compliant anonymization
- **Service eligibility**: age requirements + patch test validation
- **Deposit system**: 3-strike rule for late cancellations, 24-hour threshold
- **Scheduling**: default hours, holiday overrides, time blockers
- **Loyalty & discounts**: stamp-based loyalty, time-based and milestone campaigns
- **Portfolio gallery**: S3/R2 storage with tag/category filtering
- **CardDAV sync**: profile photos synced to SabreDAV contacts
- **Admin notifications**: priority-sorted queue with bell icon, `/notifications` page, acknowledge flow
- **User notification preferences**: per-channel toggles (email, SMS, browser) in account settings
