Kann ich AllTrails Plus vibecoden?

Build a closest honest personal substitute for AllTrails Plus in an empty repository.
Use Next.js 15, TypeScript, SQLite, MapLibre GL, and user-supplied map and travel APIs; do not offer alternative stacks.
The core loop is: organize user-imported GPX routes and trip notes, map user-entered places and reservations, and keep an offline itinerary without copying proprietary trail data or claiming live availability.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create trips, days, places, reservations, notes, documents, packing items, and emergency contacts.
Geocode only user-entered places and display them through MapLibre with cached trip-area tiles where allowed.
Parse forwarded reservation text locally into editable fields without logging message content.
Build a day timeline, route overview, conflict warnings, timezone display, and offline printable itinerary.
Allow manual updates for delays and reservations and label all external data with source and timestamp.
Export a complete trip bundle as JSON, calendar file, Markdown, and PDF.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out live flight, hotel, award, or ticket inventory.
Deliberately leave out commercial turn-by-turn navigation and global offline maps.
Deliberately leave out booking guarantees, disruption rebooking, and traveler support.
Finish by running the tests and listing the exact commands used.

Antworte mir auf Deutsch. Oberfläche, Kommentare und README auf Deutsch, alle Bezeichner wie Tabellen, Spalten, Variablen, Routen und Dateinamen bleiben Englisch.
