ControlTheme

Remarks

Loaded as UserAgent, which is the whole design. A game's own stylesheet is Author and beats this at equal specificity, so restyling a button is one rule rather than a fork of this file — and a rule that only names button is enough, rather than one that has to out-specify whatever this happened to write. That is the reason the cascade has three origins, and this is the first thing in the engine to use the first of them.

⚠ Colours go through custom properties and geometry does not. A theme wanting different colours sets nine values on the root; one wanting different shapes writes rules, because there is no useful token for "a switch's knob is a circle". The split is where it is because recolouring is what nearly every application does and reshaping is what a few do thoroughly.

⚠ The layout defaults are CSS's, so a container with no flex-direction is a row — LayoutStyleBuilder starts from CSS's initial values rather than from Yoga's, which differ in four places. Every rule below that wants a column therefore says so, and a rule that reads as redundant beside a browser stylesheet is not.

box-sizing: border-box is set here on everything, which is the one place it can be: LayoutStyleBuilder's own remarks say the property belongs in a user-agent stylesheet where an author can see and override it rather than baked into the bridge where they cannot. This is that stylesheet. Without it a control's declared height is the height of its content and every padded control comes out taller than it says.
