Planning Ahead

A single Day Summary entry as it moves between invitation, response, the live event window, and history — plus the loop that turns an empty day into a suggestion.

States

State	Meaning
NoPlan	The day is empty — suggestions are offered.
Invited	Shown in grey — awaiting the user's response.
Accepted	Shown in black — user joined or accepted.
Rejected	Shown in grey with strikethrough.
Ongoing	Today's event, highlighted blue with a live countdown.
Past	Event has ended; available from group History.
Shipped	Empty day dismissed from the list — not an RSVP action.
OpenToSuggestions	User declared availability via the `/maps/availability` call.

Reading the diagram

Visual treatment tracks state directly: Invited renders grey, Rejected renders grey-strikethrough, Accepted/Ongoing render black, and Ongoing is additionally highlighted blue with a live countdown.
Shipped is a dismissal, not a cancellation — it only removes the empty day from the list, it never touches a real RSVP.
OpenToSuggestions posts to /maps/availability and re-enters the normal invitation flow the moment a match is found.
