🎨 Export a Tailwind source entry as flowbite-vue/tailwind.css

Closes #469. Closes #465.

Since #482, index.css holds only the components' own CSS, and the app's Tailwind build generates the utilities. To do that, the getting-started guide told apps to scan the built package:

@source "../node_modules/flowbite-vue/dist";

That scans minified JavaScript, so what Tailwind finds depends on how the build was minified:

• The build escapes the quotes in FwbToggle's after:content-[""], so this setup never generates that class. It has no visible effect today, because every after:* utility already sets content, but the next class like it may not be so lucky.
• Apps have to hand-write a path into node_modules, relative to their CSS file.

#469 also describes about 81 unused utilities from the tailwind-merge tables in dist. That stopped with #481, which no longer bundles tailwind-merge.

Fix

 /* app style.css */
 @import "tailwindcss";
 @import "flowbite-vue/index.css";
-@source "../node_modules/flowbite-vue/dist";
+@import "flowbite-vue/tailwind.css";

/* src/tailwind.css, exported as flowbite-vue/tailwind.css */
@source './components';
@source not './components/**/tests';

The entry ships from src/, which is already in files, and points Tailwind at the component sources instead of the build. src/standalone.css imports it instead of repeating the two @source lines, so standalone.css and Tailwind apps scan the same sources.

@source not needs Tailwind CSS v4.1 or newer; on 4.0 the import fails the build. Without the exclusion, the entry would also generate 10 utilities that only component tests use, so the guide and CHANGELOG.md state the 4.1 requirement instead.

The entry doesn't help apps that use a prefix (@import "tailwindcss" prefix(tw);): the components use unprefixed classes, so a prefixed build generates none of them. The guide points those apps to standalone.css, imported before @import "tailwindcss" prefix(tw);. It supplies the unprefixed utilities, and its theme variables don't clash with the app's prefixed ones. Importing it first puts its utilities and preflight before the app's in each layer, so the app's utilities (for example tw:rounded-none on FwbCard) and base styles win over them.

The getting-started guide uses the new import, and now answers #465: index.css puts its CSS in its own components.flowbite-vue layer, so the app's utilities, including responsive ones like lg:mb-16, win whichever file is imported first, without a layer(...) wrapper. The guide also had the wrong Node.js requirement (18 instead of 22.12, the engines minimum) and an intro describing vanilla Flowbite's JavaScript file; both are fixed.

docs/pages/nuxt.md tells Nuxt apps running Tailwind to add the same import. CHANGELOG.md and CONTRIBUTING.md are updated.

✅ Verification

	main	This PR
flowbite-vue/tailwind.css	❌ not exported	✅
Guide setup generates after:content-[""]	❌ no	✅ yes
dist/standalone.css		byte-identical
Node.js requirement in the guide	18	22.12

• check:pack now compiles @import 'flowbite-vue/tailwind.css' from a production-only install of the packed tarball. It checks that the components' utilities are generated and that utilities only component tests use are not. Without the export it fails with "./tailwind.css" is not exported under the condition "style".
• The standalone.css tests in css.spec.ts now run through the entry.
• typecheck, lint, tests (452), check:package, check:pack and the docs build pass.

Apps that keep the old @source line still work. Renaming or moving src/components would now break the entry for apps, which check:pack catches. Reverting is a plain revert.

Summary by CodeRabbit

• New Features

Walkthrough

The package exports a Tailwind CSS source entry that scans component sources and excludes component test directories. Consumer setup documentation uses the entry, and the packed-package check compiles it and verifies generated utilities.

Changes: Tailwind source entry

Layer / File(s)	Summary
Add and wire the Tailwind source entry src/tailwind.css, package.json, src/standalone.css	The package exports flowbite-vue/tailwind.css. The entry directs Tailwind to scan component sources while excluding component test directories. The standalone stylesheet imports this entry.
Document consumer setup docs/pages/getting-started.md, docs/pages/nuxt.md, CHANGELOG.md	The Tailwind v4 setup guidance imports the exported entry. The quickstart also updates its introduction, minimum Node.js and Tailwind CSS versions, cascade-layer guidance, prefix limitation, and step numbering.
Check the packed Tailwind entry scripts/check-pack.mjs, CONTRIBUTING.md	The packed-package check compiles the exported CSS entry and fails if .bg-blue-700 is absent or .bg-red-500 is generated. The contributor guidance describes this check.

Full details: Title check

Explanation

The title names the main change: a new Tailwind source entry exported as flowbite-vue/tailwind.css. The raw summary confirms the package export map exposes ./tailwind.css, src/tailwind.css adds the source entry, and the docs and standalone.css use it. The title is specific and matches the primary change, and the conventional 'feat(css):' prefix is accurate for a new export.

Full details: Linked Issues check

Explanation

[#469] The PR adds src/tailwind.css with @source './components'; and @source not './components/**/tests';. package.json exports ./tailwind.css to ./src/tailwind.css. src/ is already in files. The getting-started guide and docs/pages/nuxt.md tell Tailwind v4 apps to import flowbite-vue/tailwind.css. The guide states the Tailwind CSS v4.1+ requirement. scripts/check-pack.mjs verifies the packed entry by compiling it with Tailwind. The export is not needed for the optional manifest alternative in the issue. [#465] The PR documents that index.css places component CSS in its own components.flowbite-vue layer, so app utilities, including responsive ones, win without a layer(...) wrapper. The guide documents the isolation behavior and the import order. The prefixed-build case points to standalone.css, which imports the same entry. The Node.js requirement correction (22.12) matches the package engines field. Evidence came from the whole-PR summary and the earlier review. The layer structure of the built index.css was not re-read in this pass. The previous PASS result remains supported.

Full details: Out of Scope Changes check

Explanation

The changes support [#469] or [#465]. They include the new export and source entry, standalone.css reuse of that entry, the check:pack coverage for the entry, documentation of the import and CSS layer behavior, the Nuxt guide update, and the CHANGELOG and CONTRIBUTING updates. The check-pack.mjs change adds coverage for the new export and does not alter unrelated behavior. The Node.js and introduction corrections in the getting-started guide relate to setup guidance for the same issues. No unrelated implementation change was found in the reviewed summary.

Review comments at @docs/pages/getting-started.md:
- Line 94: Update the Tailwind stylesheet guidance in the getting-started
documentation to cover apps using prefix(tw): explain how to provide the
unprefixed utility classes required by Flowbite Vue components, and document the
preflight implications of using standalone.css as a fallback. If the project
provides an unprefixed utilities stylesheet, describe that supported option
instead; verify the available stylesheet behavior rather than assuming an API or
changing component classes.

Review comments at @src/tailwind.css:
- Line 7: Make the `@source not` directive compatible with the supported
Tailwind version: remove it to support Tailwind 4.0, or update the setup
guidance to require Tailwind 4.1 or later. Ensure the chosen version requirement
matches the directive used in `tailwind.css`.
- Line 6: Replace the `@source './components'` approach in the Tailwind
stylesheet with a PnP-compatible way to discover component classes when the
stylesheet is loaded from a ZIP archive. Ensure utilities used only in
components are included, using a supported source-resolution mechanism without
assuming the ZIP path is directly readable by Tailwind’s scanner.
