The bar's background is the one surface a user picks -- twelve colour names, which each theme resolves to twelve of its own colours. Forty-eight backgrounds, and the links and status icons were drawn on all of them in a single token, `--btn-text`, which is near-black in three of the four themes. Night's `--brown` is #451212. A near-black glyph on it is 1.33:1. Nine of night's twelve colours and seven of amber's sat below 4.5:1, and twelve of the forty-eight below 3:1 -- icons the same colour as the bar behind them. So the foreground is measured against the background the theme actually resolved, choosing between that theme's own `--btn-text`, `--black` and `--white`. Its own, not literal ones: a white pixel in night mode undoes the dark adaptation the theme exists to protect, so night's "white" is #ff8a8a. Measuring at runtime rather than shipping an `--on-red` token per colour also means the custom YAML themes still ahead get this for free. Nothing is below 3:1 any more and the worst case is 3.27:1, up from 1.33:1. No combination is worse than it was. Ten of the forty-eight are still under 4.5:1 and no foreground will lift them: a monochrome theme resolves all twelve names onto one ramp, and a mid-tone of a hue cannot carry text of that same hue. That shortfall is in the palette, so /theme-sample now draws all twelve bars with the measured ratio printed beside each one, calling out the ten -- it is a decision to make while looking at them. The WCAG primitives move to themes/contrast so theme code can measure a colour without importing Common.js, which pulls in half the component library. Common.js forwards `contrastRatio` with a delegating function rather than a bare re-export: six specs mock it with `{...jest.requireActual('./Common')}`, the spread invokes every getter, and those spreads run re-entrantly while the module is still evaluating -- a re-export getter fires before its import binding exists and takes the whole suite down. Tested: navColors.test.js measures all forty-eight against the palette parsed out of tokens.css, and holds Nav.js to the call by source since neither bar is reachable from a test that could measure it. ui-layout.cy.js measures the painted result in a real browser in all four themes and holds it against the number the component reports. Reverting to the fixed foreground reddens four jest cases and three cypress ones. 1115 jest / 62 suites, 177 in ui-layout.cy.js, clean npm run build. |

Getting Started with Create React App
This project was bootstrapped with Create React App.
Available Scripts
In the project directory, you can run:
npm start
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
npm test
Launches the test runner in the interactive watch mode.
See the section about running tests for more
information.
npm run build
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
npm run eject
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will
remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right
into your project so you have full control over them. All of the commands except eject will still work, but they will
point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you
shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't
customize it when you are ready for it.
