Renders the real templates every send function uses (claim approved, membership invoice, invoice reminder) against hand-built placeholder context -- no real Member/ClubMembership/DuesInvoice row needed, so nothing here can leak real data. Each card shows the subject line and toggles between the HTML render (in an iframe, so the email's own markup can't clash with the page's) and the plain-text body, using the same bg-steel pill-toggle pattern as the news preview's NL/EN switch (generalised to .view-toggle-btn, kept .news-lang-btn as an alias). Admin-only, alongside Club identity in Settings. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01ECGMEwrc2k4D8VQuwjstj9

"""Sample renders of every branded email this app can send -- the Settings >
|
|
Email previews page (management/templates/management/email_previews.html),
|
|
so a club can see exactly what a member/parent receives without anything
|
|
actually being sent.
|
|
|
|
Each entry renders the *real* templates the real send functions use (see
|
|
members.services.claims.send_claim_approved_email and
|
|
club.services.invoicing.send_invoice_email/send_reminder_email) against a
|
|
hand-built sample context -- never a real Member/ClubMembership/DuesInvoice
|
|
row, so this needs nothing from the database beyond the current club itself,
|
|
and can't leak anything real. Adding a new branded email later means adding
|
|
one entry here, not touching the view or template.
