[Unreleased]

Edit-in-place: double-click any element (text, heading, list item, table cell, table header, collapsible title, image src/alt) to edit it inline. Auto-saves to disk (~400 ms debounce) with a toolbar status indicator.
Live JSON view (View ↔ JSON toggle). Two-way bound to the rendered document; edit JSON directly with Cmd+S or blur to commit.
Native Markdown viewer with GFM (tables, blockquotes, code, task lists, images, hr) and MD ↔ Paged toggle.
Welcome screen with recent files, drag-drop hint, and dark-mode coverage.
Sidebar thumbnails (per-page mini layout preview).
Search panel with multi-match highlighting and keyboard navigation.
Help overlay (?) with grouped File / View / Edit & Navigate shortcuts.
JSON Schema (spec/jdf-schema.json) and spec/examples/hello-world.jdf.
CLI (tools/jdf-cli/): validate (Ajv-based), import (md→jdf).
Header/footer with element children (not just template text).
Internal link navigation (#page-N → jump to page N).
TOC click-to-navigate with hierarchical depth filter.
PDF export now respects meta.pageSize/pageOrientation (was hardcoded A4).
PDF export now applies style.color to text via set_fill_color.
PDF export TOC: iterates document headings into a real TOC (was placeholder).
Auto-save flushes pending writes on window close (onCloseRequested).
Recent files self-clean: invalid paths are removed on failed open.

Type ↔ renderer mismatches that silently broke many features:
- Heading: heading: 1-6 now renders as <h1>-<h6> (was always <p>).
- List: listType: "ordered" now renders <ol> (was always <ul>).
- RichText: bold/italic/underline/strikethrough/color/fontSize/fontFamily per run.
- Table: headers array, borders: bool|object, alternatingRowColor, column alignment.
- Image: both src and resource, fit modes (contain/cover/fill/none).
- Header/footer: content template variables ({{pageNumber}}, {{title}}, …) actually evaluated.
- Shape: stroke accepts string or {color, width} object.
text.align field now applied (was ignored — only style.textAlign worked).
Footer no longer overlaps last element on long pages (page padding accounts for header/footer height).
Markdown→JDF: tables, blockquotes, links, images, hr, GFM strikethrough/tasklists.
validate_document performs element-level schema checks with errors and warnings separation.
Untracked .DS_Store files removed from the repo.

The "Edit" mode toggle button. Editing is implicit on .jdf files via double-click; no global mode flag.

Initial release: JDF format spec, Tauri viewer, PDF/Markdown import, PDF export, search/sidebar/zoom/dark mode, file associations.
