== Background
While working on getting night mode enabled for Wikistories we discussed a situation where Wikistories highlights text in yellow. In this situation the night mode should mimic light mode. This is also likely to be necessary for the reference preview in the mobile site, which always uses the night theme.
Ideally, it should be as simple as adding the rule `color-scheme: light;` to the content or adding a class.
Perhaps for background and color in particular we may want to define https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/light-dark
We may need direct access to night mode / light mode design tokens. e.g. `var( --color-base-night )` and `var( --color-base-light )`
