9/// Per-widget colour overrides for [`TextField`]. When set via
10/// [`TextField::with_theme`], paint reads from these instead of
11/// the ambient [`crate::draw_ctx::DrawCtx::visuals`]. Lets callers
12/// theme a single field to match a dialog palette without forking
13/// the global visuals.
14///
15/// Any field set to `None` falls back to the corresponding
16/// `visuals()` colour, so themes can override just what they need
17/// (e.g. background + border for a dark-panel field that still
18/// wants the ambient selection / cursor highlights).
