// Conservative update of your working file:
// - stores up to 8 snapshots (capitalOneOffersSnapshots_v2 -> v3 change only in MAX_SNAP)
// - fixes "Show List" restore when overlay is hidden (use display:none instead of remove())
// - preserves all parsing, diff logic, filters, and Open behavior unchanged
