Mail templates (6 templates touched): - New shared `_styles.ts` exports a robust font stack starting with Arial/Helvetica so mail readers that lack -apple-system and BlinkMacSystemFont don't fall back to Monospace (observed in at least one webmail client). - `fontFamily` is now set on every text-bearing element, not only on `<Body>`, because some clients (Outlook, several webmail readers) do not inherit body CSS into nested sections. - ASCII substitutions are gone: "Ueber" → "Über", "fuer" → "für", "bestaetigen" → "bestätigen", "uebernehmen" → "übernehmen", "verlaesslich" → "verlässlich". - InviteEmail + NewsEmail buttons switch from the off-brand yellow (#f0b84b) to the brand dark green so the CTA matches the header. /invite form: - InviteState gains an `attempt` counter plus echoed checkbox `values`, mirroring the /register and /onboarding fix from earlier branches. A failed submit no longer wipes the Datenschutz / Adressbuch-Opt-In ticks. Passwords stay empty for security. - Field error <p> elements gain role="alert" + aria-live="polite" so screen readers announce validation failures on submit. Inputs use aria-describedby to link to error / helper text. Profile validation: - Telephone numbers must match a permissive pattern that still rejects obvious garbage (previously "abc-123-not-a-phone" was accepted). - Postal codes must match an alphanumeric pattern of 3–10 chars (previously "ABCDE" was accepted). - Child date-of-birth is now validated via superRefine: it must be a parseable date, not in the future, and not before 1900. Previously a kid born in 2030 was accepted. - The three Profil server actions now surface the first Zod issue message instead of generic "Ungültige Eingabedaten." toasts. Misc: - "fuer" → "für" in the Adressbuch page subtitle. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
