CKEditor 5 SOS demo

Small CiviCRM extension demonstrating how a site-specific module can customize the main ckeditor5 extension through its crmCkeditor5Config event.

The demo mirrors the settings from themes/sos_mjml:

• Roboto with Arial and sans-serif fallbacks;
• email font sizes: 10, 11, 13, 14, 18 and 20 px;
• SOS pink #EA148C;
• SOS blue #00577B;
• yellow #FFCF1A;
• light blue #2E78CC;
• white and black.

The bundled Roboto files are copied unchanged from the theme. Font, size and color choices made through the toolbar are stored as inline CKEditor content so the email output does not depend on editor-only preview CSS.

Dependency

This demo requires a ckeditor5 build providing the crmCkeditor5Config event. CiviCRM currently checks that the extension is enabled, but does not enforce dependency versions declared in info.xml.
