v0.1.0 — initial release

First public release of Pagewright.

A local-first book editor for Markdown — CodeMirror on the left, true paged A4 preview on the right via paged.js. Multi-chapter project model. Atomic saves with ETag conflict detection. Position-stable hot reload.

What's in 0.1.0

• Two preview modes (continuous + paged.js A4)
• 1.5 s autosave + atomic writes (temp file + os.replace)
• ETag-based conflict detection with Reload / Overwrite / Cancel dialog
• 3× exponential-backoff retry on transient saves
• Outline-driven navigation (heading click → cursor jump + preview scroll)
• Eight semantic callouts with theme-overridable labels
• Pluggable theme system (theme.css + optional theme.yaml + optional chapter_opener.html)
• Bundled default theme — clean modern paper-on-cream
• Runnable example book in examples/sample-book/
• Dark mode (auto / light / dark)
• Command palette (⌘K), filterable sidebar (⌘/), keyboard shortcuts throughout
• 68 pytest tests, CI on Python 3.10 / 3.11 / 3.12
