// Utils/InspectionPDFGenerator.swift
|
||||
// -----------------------------------
|
||||
// Generates a PDF inspection report that mirrors the web app's layout.
|
||||
//
|
||||
// Layout (portrait, US Letter 612×792 pt):
|
||||
// • Dark header band — title + "Page N"
|
||||
// • Score banner — coloured score + PASS/FAIL
|
||||
// • Meta table — facility, area, date, template, inspector, status
|
||||
// • Form fields — 12-col grid, answered fields only, section headings,
|
||||
// photo fields render the actual image
|
||||
// • Inspector notes — if non-empty
|
||||
// • Footer — generation date
|
||||
//
|
||||
// Photo fields require a network fetch for server-synced photos, so PDF
|
||||
// generation is async: all images are pre-fetched into memory before the
|
||||
// synchronous UIGraphicsPDFRenderer drawing closure runs (PDFKit drawing
|
||||
// callbacks cannot be async).
