🌟 Allow customization of default email styles (text color, link appearance) #1141
Description
Is your feature request related to a problem? Please describe.
While email templates are customizable in Hi.Events, the default styles applied to all emails are hardcoded and cannot be changed from the UI. In particular, the default body text color (#718096, a grey-purple) and link styling (underline only on hover) cannot be overridden without editing server-side files, making it hard for organizers to ensure emails match their branding out of the box.
Describe the solution you'd like
Provide a way to configure default email style settings from the organizer or event settings, such as:
- Body text color
- Link color and underline behavior
- Accent / primary color (used for buttons and headings)
This could be implemented either as dedicated style fields in the organizer settings, or as a custom CSS block in the email template editor.
Additional context
The default styles come from resources/views/vendor/mail/html/themes/default.css, which is a global file affecting all email types.
