// - The only way of using it with `views::StyledLabel` is to use a
// `StyledLabel::RangeStyleInfo` with a `custom_font`. Setting this font for
// the entire label requires re-specifying the `custom_font` for _all_
// `StyledLabel::RangeStyleInfo`s.
// - …excluding links, which cannot have a `custom_font`:
// https://crsrc.org/s?q=%22CHECK(!style_info.custom_font)%22
// Links need to use the default system font of `IDS_UI_FONT_FAMILY_CROS`,
// which is Roboto.
//
// Use a text style of `views::style::TextStyle::STYLE_BODY_2` (14pt with 20pt
// line height) instead, which matches `kCrosBody1` but uses Roboto instead of
// Google Sans. This also keeps the font consistent with links.
//
// TODO: b/256663656 - Use Google Sans Text here, preferably by updating
// `IDS_UI_FONT_FAMILY_CROS`.
//
// Using a `views::style::TextContext` of `CONTEXT_DIALOG_BODY_TEXT` with the
// aforementioned text style will result in a `ui::ColorId` of
