mega-plant/scripts/setup-job-cards-collection.mjs

// Create the `job_cards` PocketBase collection (idempotent).
//
// A job card is one stretch of work on one vehicle: a mechanic scans the vehicle's QR to
// START the job, scans it again to FINISH it and says what the odometer reads, what kind
// of work it was (service / breakdown / general repair) and what was done.
//
// Not wiped by the seed: job cards are history that exists nowhere else.
//
// Usage: node scripts/setup-job-cards-collection.mjs
