A cover photo now crowns the whole sheet — repositionable, up to four with an auto-collage — and every section is its own expand/collapse card, like the When card you liked. Repeat expands smoothly inside its card. Invite & location tightened to your notes.
What are you planning?
One card open at a time keeps the sheet short no matter how much a host fills in. The cover sits above everything; the handle floats on top of it so it still drags as a sheet.
The top of the sheet is the invitation to add one — nothing else lives up there.
Like Instagram — drag to pan, pinch or slide to zoom, so tall or wide photos still sit right in the banner.
Add 1–4 photos; the banner lays them out evenly on its own — no fiddling.
The same contained card, expanded. This is what tapping any collapsed card reveals.
