Bump postcss-selector-parser, fumadocs-ui and tailwindcss

[dependabot]

Removes postcss-selector-parser. It's no longer used after updating ancestor dependencies postcss-selector-parser, fumadocs-ui and tailwindcss. These dependencies need to be updated together.

Removes postcss-selector-parser

Updates fumadocs-ui from 14.6.1 to 16.15.4

Release notes

Sourced from fumadocs-ui's releases.

fumadocs@16.15.4

• @​fumadocs/base-ui@​16.15.4
• fumadocs-core@16.15.4
• fumadocs-ui@16.15.4

Fix Next.js <Link> not scrolling to top under docs layouts

The page container rendered <main style="display: contents">, which Next.js' scroll handler treats as a hidden element: display: contents generates no box, so its getBoundingClientRect() is all-zero, indistinguishable from display: none. The handler skips it (and the sticky TOC siblings) without ever descending into children, dropping the scroll-to-top on navigation entirely.

The <main> element in Docs, Notebook and Flux page containers is now a real grid item (display: grid; grid-area: main) wrapping the unchanged #nd-page article, which centers via the grid instead of mx-auto. Rendering is identical, but if your custom CSS has element rules on main that were previously inert, they now apply.

fumadocs@16.15.3

• @​fumadocs/base-ui@​16.15.3
• fumadocs-core@16.15.3
• fumadocs-ui@16.15.3

Fix duplicated search result for pages whose description repeats in the content

Pages generated by Fumadocs OpenAPI emit the operation description as both the page description and a content section, so every endpoint page listed the same line twice in the search dialog. Search indexing now skips the page description when an identical content record exists, keeping the record with the heading anchor.

Fix #3509

Remark LLMs: export a component with output: "function"

With output: "function", _markdown becomes a component instead of a string: Markdown content is still stringified at compile time, while JSX elements stay as JSX, receiving their original props.

// fumadocs-mdx collection config
postprocess: {
  includeProcessedMarkdown: { output: 'function' },
},

Render it with renderToMarkdown from fumadocs-core/server. Elements resolve from props.components: a component can call asMarkdown() to output its own Markdown form, other components (including missing ones) are serialized as JSX syntax.

import { renderToMarkdown } from 'fumadocs-core/server';
const { _markdown: Content } = await page.data.load();
const text = await renderToMarkdown(<Content components={getMDXComponents()} />);

getText('processed') keeps working: it renders the component for you, with an optional components map:

const text = await page.data.getText('processed', { components: getMDXComponents() });

Supported in bundler collections with both compilers, and in dynamic: true collections & @fumadocs/satteri/local-md with the Sätteri compiler.

Updates tailwindcss from 3.4.19 to 4.3.3

Release notes

Sourced from tailwindcss's releases.

v4.3.3

Fixed

• Support --watch --poll[=ms] in @tailwindcss/cli when filesystem events are unreliable or unavailable (#20297)
• Canonicalization: match arbitrary hex colors against theme colors case-insensitively (e.g. bg-[#fff] and bg-[#FFF] → bg-white) (#20298)
• Prevent Preflight from overriding Firefox's native iframe:focus-visible outline styles (#20292)
• Ensure theme('colors.foo') in JS plugins resolves correctly when both --color-foo and --color-foo-bar exist (#20299)
• Ensure fractional opacity modifiers work with named shadow sizes like shadow-sm/12.5, text-shadow-sm/12.5, drop-shadow-sm/12.5, and inset-shadow-sm/12.5 (#20302)
• Parse selectors like [data-foo]div as two selectors instead of one (#20303)
• Ensure @tailwindcss/postcss rebuilds when a preprocessor like Sass changes the input CSS without changing the input file on disk (#20310)
• Ensure CSS nesting is handled even when Lightning CSS isn't run, such as in @tailwindcss/browser and Tailwind Play (#20124)
• Prevent achromatic theme colors from shifting hue when mixed in polar color spaces like oklch (#20314)
• Ensure --spacing(0) is optimized to 0px instead of 0 so it remains a <length> when used in calc(…) (#20319)
• Load @parcel/watcher only when needed in @tailwindcss/cli --watch mode, so one-off builds and --watch --poll work when @parcel/watcher can't be loaded (#20325)
• Use explicit platform fonts instead of system-ui and ui-sans-serif so CJK text respects the page's lang attribute on Windows (#20318)
• Prevent @tailwindcss/upgrade from rewriting ignored files when run from a subdirectory (#20329)
• Ensure earlier @source rules pointing to nested files are scanned when later @source rules point to files in parent folders (#20335)
• Prevent @tailwindcss/vite from triggering full page reloads when scanned files are processed by Vite but haven't been loaded as modules yet (#20336)

v4.3.2

Fixed

• Support bare spacing values for auto-rows-* and auto-cols-* utilities (e.g. auto-rows-12 and auto-cols-16) (#20229)
• Prevent @tailwindcss/cli in --watch mode from crashing on Windows when @source points to a directory that doesn't exist (#20242)
• Prevent @tailwindcss/vite from crashing in Deno v2.8.x when context.parentURL is not a valid URL (#20245)
• Ensure @tailwindcss/cli in --watch mode rebuilds when the input CSS file changes in an ignored directory (#20246)
• Allow @variant rules used in addBase(…) to use custom variants defined later (#20247)
• Prevent @tailwindcss/vite from crashing during HMR when scanned files or directories are deleted (#20259)
• Generate font-size instead of color declarations for text-[--spacing(…)] (#20260)
• Prevent @source patterns from scanning unrelated sibling files and folders (#20263)
• Extract class candidates adjacent to Template Toolkit delimiters like %]…[% in .tt, .tt2, and .tx files (#20269)
• Extract class candidates from conditional Maud syntax like p.text-black[condition] (#20269)
• Prevent @position-try rules from triggering unknown at-rule warnings when optimizing CSS (#20277)
• Support class suggestions for named opacity modifiers from --opacity theme values (#20287)
• Prevent type errors in @tailwindcss/postcss when used with newer PostCSS patch releases (#20289)

v4.3.1

Added

• Add --silent option to suppress output in @tailwindcss/cli (#20100)

Fixed

• Remove deprecation warnings by using Module#registerHooks instead of Module#register on Node 26+ (#20028)
• Canonicalization: don't crash when plugin utilities throw for unsupported values (#20052)
