Same-origin sub-PWA for Tuxedo field workers, fully isolated from the
main Route Commerce PWA.
- public/manifest-field.json: Tuxedo-branded manifest, start_url=/water,
scope=/water, themeColor=#14532d, no Route Commerce branding
- public/sw-field.js: scoped SW with field-shell-v1 + field-data-v1
caches (never touches main app's rc-shell-v* / rc-data-v*). Skips
any request outside /water scope. Two-cache strategy: shell
cache-first + /api/water stale-while-revalidate.
- src/app/water/layout.tsx: child layout overrides root metadata
(manifest, themeColor, applicationName, appleWebApp.title) and
mounts the field SW registration + install prompt.
- src/components/pwa/FieldSWRegistration.tsx: registers /sw-field.js
with scope=/water. Module-scoped registered flag prevents strict-
mode double-registration.
- src/components/pwa/FieldInstallPrompt.tsx: sibling of InstallPrompt,
forest-green #1a4d2e theming, fires after 4s dwell. Captures
display-mode:standalone AND navigator.standalone for iOS.
No conflict with the main app PWA: PWAInstallPrompt is mounted only
under /admin/layout.tsx, so /water routes only see FieldInstallPrompt.
Tuxedo-only by design (matches existing /water single-tenant hardcode).
