Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Turn each workspace into a left-to-right strip of sibling panes, where `Cmd+D` splits the focused pane to the right, `Cmd+Opt+N` opens a new sibling pane to the right at the default pane width, and `Cmd+T` still creates a new surface inside the focused pane.

The top-level unit is a `pane`, not a nested split tree. Inside each pane, cmux still supports horizontal `surfaces` the same way Bonsplit does today. + +This keeps the top level closer to niri while preserving cmux's existing surface model.
