The "Approval Gates" section in `SENDER_PDF_TOOLBAR_PLAN_EN.md`
was updated to include a new "Notes" subheading. A checklist
item was added under this section to indicate that visual
polish for the toolbar (e.g., icon sizing, balance, and
spacing adjustments) is still pending. This change provides
clarity on outstanding design tasks.
Introduce a detailed migration plan to design and integrate a reusable toolbar component for the `SenderPdfImageEditor` in the `EnvelopeGenerator.Server` project.
The toolbar will support page navigation, zoom in/out, PDF download, and print functionality while preserving existing signature add/remove/drag-drop behavior.
The plan includes:
- Creation of a new `SenderPdfImageEditorToolbar` component.
- Updates to `.razor`, `.css`, and `.js` files.
- A non-regression strategy with incremental feature additions and manual black-box testing after each stage.
The migration is divided into five stages:
1. Visual toolbar skeleton.
2. Page navigation.
3. Zoom in/out with mouse override.
4. Download original PDF bytes.
5. Print output.
Approval gates are defined to ensure functionality is implemented correctly and regressions are avoided.
