frame allocs: a click is not a frame, a reducer is its dispatch's, a capped push is bounded; ludic.photo at 0

The analysis made every component function a frame root, event handlers (cmp_x_on_delete) too, and
every reducer, whether its action is dispatched every frame or once a trip: a component's 'on'
handlers are no longer roots, and a dispatch is an edge to its action's reducers, so a reducer
counts only when frame code dispatches it. A push into a field declared @max(n) is bounded by the
fence's own check and no longer counted. Maroon Lake: frame_allocs 395 -> 337, frame_keeps 188 -> 169.

ludic.photo: the roll's order and a page of it are kept lists refilled in place (the pack's page
asked for both every frame), its kept lists say @max(256), and a shot's tags, a photograph's fact
and a new roll are declared (once per shot, sale or trip). 18 allocs and 9 keeps -> 0 and 0.
