 - The unified top toolbar is now the only layout. Panel-era typed config fields and order groups are removed from the serde model (`side_*` placement/pin/pane keys, `show_settings_section` / mode overrides, and `ui.toolbar.items.order.{side_sections,actions,pages,boards,presets,tool_options,sessions}`). Authored values at those exact paths remain in `config.toml` as retired settings and no longer affect the overlay. Matching keys under `runtime-ui.toml`'s recognized `item_order` map are pruned on rewrite.
 - Public Rust types that described the side palette / panel-only toolbar order groups are gone. Downstream crates that constructed those fields must drop them; the in-repo configurator already matches this shape.

+- Stylus pressure no longer overrides the selected Marker/Textmarker or Step Marker size. Pressure-to-thickness mapping remains limited to pressure-sensitive freehand Pen strokes.

 **Notes:**
 - Requires the `tablet-input` feature at build time (enabled in default release builds).
 - Tablet input is enabled by default when the feature is compiled in; set `enabled = false` to opt out.
+- Pressure-to-thickness mapping applies only to pressure-sensitive freehand Pen strokes. Marker/Textmarker, Step Marker, and shape tools keep their selected sizes when used with a stylus.
 - `stylus_button` is the primary barrel button (`BTN_STYLUS` / 331); `stylus_button2` is the secondary barrel button (`BTN_STYLUS2` / 332).
 - Barrel button `action` values use normal action names, such as `toggle_radial_menu`, `undo`, and `redo`. Omit `action` to leave a button unbound.
