# Description of Changes
- Reduced lightweight editor JSON size:
- Omit heavy page resources and contentStreams in lazy/lightweight
flows.
- Omit form fields in lazy metadata/editor bootstrapping flows.
- Strip inline font program blobs from lazy initial payloads.
- Added page-based font loading:
- New endpoint to fetch fonts for a specific cached page:
GET /api/v1/convert/pdf/text-editor/fonts/{jobId}/{pageNumber}
- Frontend now loads page fonts alongside page data and merges into
local doc state.
- Reduced save payload duplication:
- Partial export now sends only changed pages (no repeated full-document
font/metadata payload each save).
- Preserved round-trip/export safety:
- Missing lightweight fields (resources/contentStreams) are interpreted
as “preserve existing from cached PDF.”
- Annotation semantics fixed so explicit empty annotation lists can
clear annotations.
- Fixed a regression where lazy mode could fall back to full export and
lose overlays; lazy now stays on cached
partial export path when dirty pages exist.
- Logging/noise reduction
- Transport optimization:
- Enabled HTTP compression for JSON/problem responses. (might remove
later tho in testing)
### Outcome
- Much smaller JSON payloads for giant PDFs.
- Fewer duplicated bytes over the wire.
- Page-scoped loading of heavy font data.
- Better reliability for preserving overlays/vector/background content
during export.

# Summary
- Adds desktop file tracking: local paths are preserved and save buttons
now work as expcted (doing Save/Save As as appropriate)
- Adds logic to track whether files are 'dirty' (they've been modified
by some tool, and not saved to disk yet).
- Improves file state UX (dirty vs saved) and close warnings
- Web behaviour should be unaffected by these changes
## Indicators
Files now have indicators in desktop mode to tell you their state.
### File up-to-date with disk

# Limitations
- It's a bit weird that we still have files stored in indexeddb in the
app, which are still loadable. We might want to change this behaviour in
the future
- Viewer's Save doesn't persist to disk. I've left that out here because
it'd need a lot of testing to make sure the logic's right with making
sure you can leave the Viewer with applying the changes to the PDF
_without_ saving to disk
- There's no current way to do Save As on a file that has already been
persisted to disk - it's only ever Save. Similarly, there's no way to
duplicate a file.

# Description of Changes
This pull request improves the PDF stamping feature, particularly the
text stamping functionality, by introducing dynamic variables, improving
formatting flexibility, and refining positioning logic. The changes
include backend support for dynamic stamp variables (such as date, time,
filename, and metadata), improvements to text layout and positioning,
updates to the API and frontend for usability, and localization
enhancements for user guidance.
**Dynamic Stamp Variables and Text Processing:**
* Added support for dynamic variables in stamp text (e.g., `@date`,
`@time`, `@page_number`, `@filename`, `@uuid`, and metadata fields),
including custom date formats and escaping for literal `@` symbols. This
is handled by the new `processStampText` method in
`StampController.java`.
* Implemented validation and formatting for custom date variables,
ensuring only safe formats are accepted and providing user-friendly
error messages for invalid formats.
**Text Layout and Positioning Improvements:**
* Refactored text and image stamp positioning: now calculates line
heights, block heights, and widths for multi-line stamps, and adjusts
placement logic for more accurate alignment (top, center, bottom) and
margins.
* Updated the default font size for stamps to 40pt and improved font
size handling in both backend and frontend, including validation for
positive values
**API and Method Signature Updates:**
* Extended method signatures to include additional context (such as page
index and filename) for more powerful variable substitution in stamps
**Frontend and Localization Enhancements:**
* Added comprehensive help text, variable descriptions, and template
examples to the UI, making it easier for users to understand and use
dynamic stamp variables.
* Improved accessibility and clarity in the stamp formatting UI by
disabling controls appropriately and providing clearer descriptions.

# Description of Changes
PDF editor has been impossible to access since #5169. This fixes the bug
introduced in that which made it impossible to access. The main issue
was the refactor removed the `setLeftPanelView` call.
Makes sure settings step collapses in results step
Makes sure result step doesn't always reset even in development for
baseTool
Make sure result step doesn't reset for convert
Show signature preview on hover
Place signature smaller (mkatch preview size)
Retain signature in modal on close/open
Clean up ui generally
Small bug fixes
## Summary
- add a dedicated edit table of contents tool to the React UI, complete
with bookmark editor, import/export actions, and parameter handling
- register the tool in the translated registry and extend the English
translations with the new strings
- wire up the backend endpoints through a new operation hook and
form-data serialization helpers
## Testing
- ./gradlew build

# Description of Changes
TLDR:
- Added `naturalCompare` function to handle alphanumeric sorting
- Updated `sortFiles` logic to use `naturalCompare` for filename sorting
- Passed `naturalCompare` as dependency in sorting callback
This pull request improves the file sorting logic in the `Merge` tool to
provide a more natural, human-friendly ordering of filenames (e.g.,
"file2" now comes before "file10" instead of after). The main change is
the introduction of a custom `naturalCompare` function that is used when
sorting files by filename.
File sorting improvements:
* Added a `naturalCompare` function to sort filenames in a way that
handles numeric portions naturally, ensuring files like "file2" are
ordered before "file10" (`frontend/src/core/tools/Merge.tsx`).
* Updated the file sorting logic to use `naturalCompare` instead of the
default `localeCompare` when sorting by filename
(`frontend/src/core/tools/Merge.tsx`).
* Ensured the `sortFiles` callback properly depends on the new
`naturalCompare` function (`frontend/src/core/tools/Merge.tsx`).
Note: the sort on upload is natural sort (at least I think so I haven't
checked the code), this is only relevant after upload, and you click the
sort button again
