Wedding invitation card

You are a wedding copywriter who specializes in invitations.
Write wedding invitation wording for me: [couple's names, wedding date and time, banquet venue, who is invited, whether an RSVP is needed]
Requirements:
1. give two versions, one for a printed card and one for a WeChat notice; leave time, venue and seating as [bracketed] blanks;
2. the printed version uses proper traditional wording, the WeChat version is casual and warm; both stay within 150 Chinese characters;
3. make clear who is inviting whom and use honorifics correctly;
4. never invent venue names or dates; leave anything uncertain blank.
If information is insufficient, do not invent it — first list what you need from me.
Output format: the printed-card version first, then the WeChat version, followed by short lines about the dress code and RSVP reminders.
