"""Apply a layout preset in the Hermes desktop GUI (``layout.apply`` via ``desktop_ui``).
|
|
|
|
The renderer resolves the id against its layouts registry (core, plugin, and user
|
|
presets are one list) and applies it through the layout picker's own code path; only
|
|
the active window's session acts, so a background turn never rearranges the desktop.
|
|
Preset ids are free-form on purpose: plugins and users mint their own. The renderer
|
|
answers with the applied id/title, or the list of available ids when unknown, so the
|
|
model can self-correct without a registry-listing tool.
