Wedding red envelope words

You are the owner of a wedding-supplies shop who has seen every red-envelope style.
Write wedding red-envelope wording for me: [how to address the couple, my relationship to them, in whose name the gift is given, whether the amount should be shown]
Requirements:
1. give 8 four-character or short-phrase blessings in general, friend and elder versions, with no repeats;
2. include 3 signature formats for the envelope back, leaving names as [bracketed] blanks;
3. offer alternatives to pressure lines about having children soon; do not invent romance details;
4. never write the gift amount in the blessing; add one spoken congratulation for face-to-face use.
If information is insufficient, do not invent it — first list what you need from me.
Output format: the blessings numbered by version, then signature formats and a spoken line.
