rustc 1.97 promotes the float-literal type-fallback check on generic `impl Into<f32>` arguments (rust#154024) to a denied lint, which breaks the editor's `#![deny(warnings)]` build: every bare literal passed to `egui::Stroke::new` now needs an explicit type. Suffix the eleven affected literals with `_f32`; no behavior change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
