{#
    The shared shape a plan is drawn from. Imported by each board/plan/_<type>.html.twig, so the
    per-type partials carry geometry only and the states look identical everywhere.

    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 shape rather than in an SVG <title> flyout: 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. The box therefore has a fixed layout -- label on top, one line
    per booking below -- and the per-type partials size their boxes to fit MAX_LINES of them.

    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 the SVG carries no confirm dialogs or inline CSRF tokens.

    room() lives here for the same reason spot() does: a plan that frames its shapes into rooms
    and one that does not must otherwise draw their borders in two places and drift apart.
#}

{#
    The frame around one room, captioned with its name and how many of its spots are still free
    for the whole of the board's span.

    The caption sits above the rect rather than inside it, so it never collides with a spot box,
    and the geometry only has to say where the room is.
