公益募款晚會邀請卡（暖調牛皮紙手繪風）

prompt

Illustrate a heartfelt invitation card for a nonprofit fundraising gala, portrait 5x7 inch. Kraft-paper textured background in warm tan, with hand-drawn colored-pencil illustrations around the border: joined hands, sprouting leaves and small paper lanterns relating to {cause_focus}. Centered headline {event_name} in a friendly hand-lettered style, followed by 'Hosted by {org_name}' in a rounded sans-serif. The middle block lists {event_date} and {venue_name} on two clean lines separated by a tiny heart divider. The bottom edge carries a gentle call to action: 'Every seat changes a life.' Limit the palette to terracotta, sage green and cream. Soft, imperfect, human linework — clearly not corporate. Print-ready flat design.
