The entriesContainer has no padding so cards fill the grid edge-to-edge;
there is no clickable empty space at the left/top/bottom of the card area
within entriesContainer. Moved rect-selection initiation into the
document-level mousedown handler so it fires when clicking on ANY
non-interactive element inside .vault (padding, grid gaps, etc.).
Interactive elements (buttons, inputs, folders bar, toolbar, etc.)
still clear selection as expected.
