Expected: After changing fontWeight on a main component's fit-content Text, each instance re-measures its own (overridden) text and its hug-width root resizes.
Actual: Instance labels keep/take the width measured from the main's text ("Button"), so instances with longer overridden text overflow or clip ("Confirm order" spills outside a 77px button).
Repro: 1) Main "Btn" = flex row, width fit-content, padding 0 16px, child Text "Label" = "Button", 14px, weight 400. 2) create_instance, set_text_content Label = "Confirm order". 3) update_styles on the main Label {fontWeight:700}. 4) get_node_info on the instance root: width ≈ width of "Button" + 32, text overflows.
Workaround: update_styles {width:"fit-content"} on each instance's Text node forces a re-measure.
Impact: One main edit silently breaks every instance with overridden text across all pages; finding the instance text nodes needs one call per instance.
