sub explain_panes($self, %args)
```

`explain_panes(where => criteria|Filter, pushdown => policy?)`.

Validate criteria and return an inspectable [`LibTmux::QueryPlan`](/en/perl/latest/reference/libtmux-queryplan/) without I/O or mutation. The plan records required fields/relations, source commands, residuals, and conditional daemon capability needs. Invalid criteria throw [`"InvalidFilter" in LibTmux::X`](/en/perl/latest/reference/libtmux-x-invalidfilter/). Executing [`"query_panes"`](/en/perl/latest/reference/libtmux-server-query_panes/) discovers the connected generation and capabilities.


```perl
    my $plan = $server->explain_panes(where => {width => {-gte => 120}});
```
