// FAILING test: digest.mjml hardcodes #7161FF instead of using {{brandAccent}}
//
// The bug: in src/emails/digest.mjml line 8 and line 22, the CSS for
// .event-item border-left and .footer a color hardcode #7161FF even though
// {{brandAccent}} is passed into the template by mailer.ts and used
// elsewhere (lines 15, 34). When BRAND_ACCENT is customized, the event-item
// border and footer links stay the default purple.
//
// The fix: replace both hardcoded #7161FF values with {{brandAccent}}.
