Overlay stack restores focus

The problem

Search is a full-screen overlay. Closing it always lands on the first poster. After a search, the user has to walk the catalog again. Back must pop a stack, not reset the grid.

The pattern that fixes it

Push { screen, row, col } when opening search. Back pops and restores that cell. The overlay is another screen on the same remote model — not a new page that forgets where you were.
