The app/Services/ directory had grown into 22 flat files at the root plus 7 uneven subdirectories — finding anything required scrolling through an alphabetical mix of small CRUD services, infrastructure drivers, and install-time utilities. This commit groups services by domain, folds Backup into a new Storage namespace, and moves framework-infrastructure and install-time helpers out of Services and into Support where they belong.
New Services layout: Documents/ (Invoice, Estimate, RecurringInvoice, Payment, Expense, Transaction, DocumentItem, SerialNumber, Currency — matches the 'Documents' navigation group); Company/ (Company, Member, Invitation); Mail/ (MailConfiguration, CompanyMailConfig); Storage/ (FileDisk, plus Backup folded in). ExchangeRateProviderService moves next to its drivers in ExchangeRate/; FontService moves into Pdf/ where it belongs. CustomerService, ItemService, CustomFieldService stay at the Services root as standalone single-file domains.
Moves to Support/: Hashids/ (library wrapper — not business logic); Setup/ (one-shot install-time utilities — stateless helpers); Pdf/ (ImageUtils, PdfTemplateUtils, plus the existing PdfHtmlSanitizer consolidated into the same subdir). These are all framework infrastructure and stateless utilities — the 'service' label never really fit them.
Namespace declarations in 29 moved files updated to match new paths. 62 consumer files (controllers, other services, tests, database factories, seeders, routes, bootstrap/providers.php) have their use statements rewritten via a literal-string replacement script — no regex meant no risk of half-matching. Three Documents services needed an explicit 'use App\Services\Mail\CompanyMailConfigService' added because the same-namespace short reference they relied on no longer resolves after the split.
Verified: composer dump-autoload, 350 tests pass (850 assertions), vendor/bin/pint clean, npm run build succeeds.
Bundle Noto Sans (Regular/Bold/Italic/BoldItalic) under resources/static/fonts/ as the default PDF face — it covers Latin, Cyrillic, Greek, Arabic, Thai and Hindi out of the box, replacing the limited DejaVu Sans fallback. Move all @font-face declarations into app.pdf.partials.fonts and include it from every invoice/estimate/payment/report template, dropping per-template font-family hardcodes and the conditional Thai locale include.
Introduce FontService + FontController to download static Noto Sans CJK packages (zh, zh_CN, ja, ko) from life888888/cjk-fonts-ttf on demand. GeneratesPdfTrait::ensureFontsForLocale primes the family before rendering and the partial emits @font-face rules for installed packages so dompdf resolves them through standard CSS — no separate registerFont() instance required. Static TTFs are mandatory because dompdf's PHP-Font-Lib does not parse variable fonts (fvar/gvar tables), which is why Google Fonts' NotoSansTC[wght].ttf rendered empty boxes.
Expose status/install via /api/v1/fonts/status and /api/v1/fonts/{package}/install with matching FONTS_STATUS / FONTS_INSTALL constants in scripts-v2/api/endpoints.ts. Flip DOMPDF_ENABLE_REMOTE default to true for remote asset loading.
