| void | setText (std::string_view text, bool preserveScroll=false) |
| Replace the buffer contents with text. By default this scrolls the view back to the top — appropriate for File→Open and similar "load a different document" flows. Pass preserveScroll=true when the replacement is a small in-place edit (e.g. canvas→text writeback after a transform drag) so the user's scroll position isn't yanked out from under them. | |

Headless editing substrate — the text buffer, cursor, undo history and syntax colorizer with no ImGui dependency.
TextEditor wraps this class and adds the ImGui rendering and input layer. Direct consumers should go through TextEditor; tests (once C3 migrates them) will construct TextEditorCore directly.
