Pull each individual's highlighted media image via webtrees'
Individual::findHighlightedMediaFile, attach as Symfony inline
parts with stable cid:avatar-<xref> identifiers, and render
border-radius:50% on the <img>. Couples on anniversaries show
both spouses' circles side-by-side.
Fallback when no image is available (privacy-hidden record, no
OBJE, external URL, unreadable file): a CSS-only coloured circle
with the person's initials. The hue is derived from a hash of
the XREF so the same person keeps the same colour across
newsletters.
Done via a NewsletterMailer subclass of EmailService that adds a
sendWithEmbeds() method — the parent's transport() and DKIM
config still apply, only the message-construction path differs.
Recurring email newsletter for webtrees 2.2+. Each enabled tree
sends upcoming birthdays of living individuals, optional marriage
anniversaries of intact couples, and a once-per-calendar-month
historical section of births and deaths of deceased individuals.
Triggered exclusively by an external scheduler (system cron,
systemd timer, etc.) hitting a token-gated HTTP endpoint — never
on visitor page loads. The "is it due?" decision is idempotent
within the configured frequency window.
Per-user subscription is integrated into the built-in
/my-account/{tree} page via a custom view + a decorated
AccountUpdate handler. Admins can add external addresses and
trigger an immediate send for testing. Email body renders in
German for German-language users; English otherwise. Birthdays
and anniversaries are formatted with the upcoming-event ordinal
age (e.g. "45th birthday" / "45. Geburtstag").
