# 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.

# 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.
