- Invalid Area "Undo" reverts the step that lost the boundary (redo after an undo, undo otherwise), checks the boundary is back and otherwise puts the step back and continues without the area; no auto-undo loop. - COUNTCLOSE / area replacement remove the count polyline outside the history instead of as an undo step of their own. - UPDATEFIELD re-evaluates the field texts of a table's *T block and reports the number actually updated. - Zoom to a counted object goes through the f64 handle_zoom_to_window. - Palette: SVG icons instead of glyph text, list cache keyed by tab id, cached result borrowed instead of cloned, "Count" as the source text. - Command-line messages go through t!/tf! with entries in all locales. - Cleanups: \n escapes, area comment, unused parameter, comment order.
