Summary

Document the current library, reading-position and bidirectional annotation workflows, replacing outdated migration, tile-layout and startup-scan descriptions.

Readest Sync documentation
├── Illustrated user guide: five Mock cloud screenshots
├── Technical and installation guides: current behavior and limits
└── Simulator guide: reproducible screenshot capture

The images use isolated synthetic fixtures and retain the Simulator · Mock label. The reader panel is explicitly identified as a simulator aid. An optional READEST_DOC_SCREENSHOTS mode in the existing integration test reproduces the captures without changing the app or interactive profile.

Evidence

• Before: README described pending Qt migration acceptance, library tiles and no startup scan; no illustrated guide or annotation workflow.
  After: User guide covers the current interface, downloads/uploads, position choices, highlights/notes and device limitations. All five 1404 × 1800 screenshots were visually checked.
• Before: Screenshot capture had no dedicated documentation checkpoints.
  After: Simulator integration test passes with capture enabled (10.83 s) and disabled (9.23 s). All local documentation/image links and git diff --check pass.

Merge Danger

Door: two-way

Documentation and optional test-only capture changes; no application behavior or persisted formats change.
