Reflect completion of phases 6a–6c in the project plan:
- Marked phases 6a (signFLOW logo), 6b (customer logo placeholder),
and 6c (grid columns + persistence hint) as completed.
- Updated dependency rule to reflect the change from
`EnvelopeGenerator.Server.Client` to `Blazor WASM Client`.
- Reiterated key decisions, including the use of `TBDD_CACHE`,
`SenderOrReceiver` policy, and `signflow.theme` in localStorage.
- Noted DevExpress 25.2.3 lacks `.dark.`-suffix files.
Introduced a customer logo section in `EnvelopeSenderPage.razor` that dynamically displays a customer logo or a placeholder when no logo is configured. The logo is fetched from the `CustomImagesService` and styled using new CSS classes in `sender-page.css`.
- Added `_companyLogo` property to store customer logo configuration.
- Updated `CustomImagesService` to fetch both app and customer logos.
- Modified `appsettings.json` to include logo paths and styles.
- Enhanced CSS for a three-section action bar layout.
- Added placeholder styling for missing customer logos.
- Updated initialization logic to load logos dynamically.
- Documented implementation details in `SF-74-PLAN.md`.
The implementation is modular and deployment-specific, allowing logo paths and styles to be updated via configuration without code changes.
