TISX — user guide

This guide is a stub. Content is coming as the docs settle.

Things this guide will cover:

• Selecting your vehicle by series / model / engine, or by VIN.
• Browsing the document tree (document type → main group → sub group).
• Reading a repair procedure — hotspot cross-references, image embedding, print layout.
• Symptom-based navigation through the complaint tree.
• Bookmarking vehicles + documents to favourites, exporting / importing.
• Toggling dark mode.

In the meantime, the project README has the data-preparation walkthrough.
