Four things, three cosmetic and one a real legibility bug. * Tags were square chips. They now have a pointed left edge and an eyelet, like a tag tied to a garment -- the shape Semantic gave them, and the reason a tag reads as a tag rather than as a small button. The point is a square rotated behind the left edge, sized so its diagonal equals the body height and its two edges meet the body at the corners. Only where something is actually a tag. `Label` carries the count badges in the Tags table too -- file, zim, channel and domain counts -- and a point on a number reads as an arrow, so the shape is behind a `tag` prop and `NameToTagLabel` opts in. * They were smaller than what they replaced: 11.5px text with 3px of padding, against Semantic's 12px and ~7px. Now 12.5px and 5px, which also keeps them a reasonable thing to tap. * Wrapped rows of tags sat on the row above, so they carry a bottom margin, plus a left margin for the point to occupy. * The text colour was unreadable in night and wrong in amber. Tags.js calculates black-or-light against the colour the user chose for each tag, and wrote the answer to `color` inline -- a declaration no stylesheet rule can outrank. Night turns a tag into an outline over a near-black page, so a near-white tag kept the black text calculated for its fill and was left legible only by its border: 1.1:1, measured. Amber replaces every fill with its own bright orange and was painting `#dddddd` on `#ff9500`, about 1.9:1, and a neutral grey in a theme whose whole point is that no other hue reaches the eye. The fix is to stop hard-coding `color` so the theme can decide: the calculated colour goes into `--label-text`, and night and amber override it alongside the fill they already override. There is no second contrast function to write, which is what this looked like it needed -- once a theme has discarded the user's colour there is nothing left to calculate against, and the answer is just the theme's own token. `.wrolpi-label-white` and `-black` moved to the same variable. Setting `color` there outranked the base rule, so amber was painting `--white` on `--text`: light orange on orange. `contrastingColor` was also picking the worse of its two options. It compared a brightness figure against a threshold, and the figure weighted the gamma-encoded bytes without linearising them, so Semantic's blue `#2185d0` got light text at 2.9:1 where dark text gives 5.3:1. Every mid-tone blue, teal and purple a user might pick sat in that band. It now measures the WCAG contrast ratio of both candidates and returns the better one, which needs no threshold at all. Tests ----- `Tags.test.js` is new, and covers the chip nothing covered: every other spec takes `NameToTagLabel` from `tagsContextFixture`, which stubs it as a function returning the name. That is how a tag could be unreadable without a single test noticing. Two of these were verified red against the inline `color`. `cy.contrastRatio()` measures text against the surface *actually* behind it, walking up to the first ancestor that paints something -- a transparent tag has no background of its own, so a naive check reads rgba(0,0,0,0) and concludes anything is legible. Twelve cases, three tag colours across four themes, at WCAG AA. Plus a test asserting the old inline-`color` version still measures below 1.5:1, so the check is provably able to fail. The gallery had label swatches in theme colours and no user-coloured tag, which is why none of this was visible in it. It has eleven now, spanning the range where the black-or-light decision flips. |

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.
