{#
    One bookable thing on the plan: a card coloured by its state, with who holds it listed inside.

    The state comes from App\Model\Spot, not from counting bookings here. That distinction is
    the fix for a real bug: a desk booked 09:00-13:00 used to render exactly like one booked all
    day on an all-day board, and carried no hx-get either -- so a second person could not book the
    afternoon at all unless they happened to narrow the span by hand first.

    Who holds what is listed INSIDE the card rather than in a title tooltip: a tooltip only
    appears on hover, so it is useless on touch and invisible when scanning the plan, which is the
    one thing a floor plan is for.

    Clicking always opens a modal: the create modal when anything is still free, the edit modal
    when it is yours (which is where changing the times and releasing live). Nothing else is
    clickable, so a card carries no confirm dialogs or inline CSRF tokens.
