+# Repository Guidelines
+
+## Project Structure & Module Organization
+- `packages/*` — TypeScript packages. Core lives in `packages/tailwindcss`; adapters/tools are under `@tailwindcss-*`.
+- `crates/*` — Rust crates (e.g. `crates/oxide`, `crates/node`). Node bindings are published from here.
+- `integrations/` — Vitest-based integration tests for CLIs/build tools.
+- `scripts/` — Release and maintenance utilities (e.g. `version-packages.mjs`).
+- `dist/` — Packed artifacts after builds; useful for local installs.
+- `playgrounds/*` — Sample apps to manually verify changes.
+
+## Build, Test, and Development Commands
+- `pnpm install` — Install JS deps. Ensure Rust toolchain via `rustup default stable` and add `wasm32-wasip1-threads`.
+- `pnpm dev` — Turbo watch builds; filter example: `pnpm dev --filter=tailwindcss`.
+- `pnpm build` — Build all packages (excludes playgrounds). Creates tarballs in `dist/`.
+- `pnpm test` — Run Rust `cargo test` and Vitest across the workspace.
+- `pnpm test:integrations` — Run integration tests (run `pnpm build` first).
+- `pnpm test:ui` — Run Playwright UI tests for browser-related behavior.
+- `pnpm lint` / `pnpm format` — Check/fix formatting and package-level lint scripts.
+
+## Coding Style & Naming Conventions
+- Prettier is authoritative: `semi: false`, `singleQuote: true`, `printWidth: 100`.
+- Indentation: 2 spaces. TypeScript files prefer `.ts`; compatibility shims may use `.cts`.
+- Naming: kebab-case file names, camelCase functions/vars, PascalCase types/classes. Rust modules use `snake_case`.
+- Run `pnpm lint` locally before opening a PR.
+
+## Testing Guidelines
+- Unit tests: Vitest; name files `*.test.ts` near the code they cover or in `src/**/__tests__`.
+- Integration: tests live in `integrations/**`; run `pnpm build && pnpm test:integrations`.
+- UI: Playwright tests via `pnpm test:ui`.
+- Rust: crate tests run with `cargo test` (also covered by `pnpm test`). Include tests with any behavior change.
+
+## Commit & Pull Request Guidelines
+- Commit messages: clear, present-tense summaries; reference issues like `#123` when relevant.
+- New features: open a discussion before investing significant work.
+- PRs must include: problem summary, rationale, and a test plan (exact commands; screenshots if UI-related). Ensure all tests pass; use `[ci-all]` in the description to run all platform suites.
+- See `.github/CONTRIBUTING.md` and `.github/PULL_REQUEST_TEMPLATE.md` for details.
+
+## Security & Configuration Tips
+- Do not commit secrets or machine-specific paths. Use `pnpm@9` (workspace-managed) and Rust stable. Turbo caches builds; when in doubt, rebuild with `pnpm build`.
+

-- Don't generate utilities when a modifier is used that would otherwise be silently ignored (e.g. `rounded-sm/[5]`, `shadow-sm/foo`, `stroke-2/50`) ([#20419](https://github.com/tailwindlabs/tailwindcss/pull/20419))
-- Only normalize top-level `and`, `or`, and `not` keywords in `supports-[…]` variants (e.g. `selector(a: not (.foo))` → `selector(a:not(.foo))`) ([#20420](https://github.com/tailwindlabs/tailwindcss/pull/20420))
-- Don't warn about Angular's `::ng-deep` and `:host-context()` when optimizing CSS ([#20434](https://github.com/tailwindlabs/tailwindcss/pull/20434))
-- Don't generate CSS for candidates containing an empty additional modifier (e.g. `bg-red-500/50/` and `group-hover/foo//bar:flex`) ([#20466](https://github.com/tailwindlabs/tailwindcss/pull/20466))
-- Sort `min-*`, `max-*`, and container query variants with decimal values numerically (e.g. `min-[40.25rem]` before `min-[40.5rem]`) ([#20512](https://github.com/tailwindlabs/tailwindcss/pull/20512))

-- Improve style invalidation performance of `group-*` and `peer-*` variants ([#20513](https://github.com/tailwindlabs/tailwindcss/pull/20513))

-## [4.3.3] - 2026-07-16
-
-### Fixed
-
-- Support `--watch --poll[=ms]` in `@tailwindcss/cli` when filesystem events are unreliable or unavailable ([#20297](https://github.com/tailwindlabs/tailwindcss/pull/20297))

-- 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](https://github.com/tailwindlabs/tailwindcss/pull/20302))
-- Parse selectors like `[data-foo]div` as two selectors instead of one ([#20303](https://github.com/tailwindlabs/tailwindcss/pull/20303))

-- 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](https://github.com/tailwindlabs/tailwindcss/pull/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](https://github.com/tailwindlabs/tailwindcss/pull/20318))
-- Prevent `@tailwindcss/upgrade` from rewriting ignored files when run from a subdirectory ([#20329](https://github.com/tailwindlabs/tailwindcss/pull/20329))

-/// When dealing with a pattern, then it could be that we end up with:
-///
-/// ```json
-/// { base: '/some/folder', pattern: 'foo.ts' }
-/// ```
-///
-/// If we just emit `!foo.ts` for the `/some/folder` path, then _everything_ else in that folder
-/// would still be walked (but the result will be ignored).
-///
-/// Instead, we have to ensure that we ignore everything in that folder _except_ for the `foo.ts`
-/// pattern.
-///
-/// This should be equivalent to:
-/// ```gitignore
-/// *
-/// !foo.ts
-/// ```
-///
-/// However, we have to be careful that we don't start ignoring files/folders that already exist.
-/// ```css
-/// @source "./some/folder/foo.ts";
-/// @source "./some/folder/bar.ts";
-/// ```
-/// Would result in:
-/// ```json
-/// { base: '/some/folder', pattern: 'foo.ts' }
-/// { base: '/some/folder', pattern: 'bar.ts' }
-/// ```
-///
-/// If we were to blindly emit `*` for each pattern, then the `.gitignore` equivalent would look like
-/// this:
-/// ```gitignore
-/// *
-/// !foo.ts
-/// *
-/// !bar.ts
-/// ```
-///
-/// This would result in ignoring the `foo.ts` file as well. Therefore we only want to insert
-/// this `*` pattern when nothing else exists yet.
-///
-/// There is another problem that we need to solve. Let's say you have a pattern that contains a `*`
-/// in the pattern:
-/// ```css
-/// @source './src/ba*/*.html';

-///
-/// This would result in
-/// ```json
-/// { base: '/src', pattern: '/ba*/*.html' }
-/// ```
-///
-/// If we now inject the `*` pattern for the `/src` folder, then we wouldn't scan any `ba*` folders
-/// (e.g. `bar` or `baz`). For this, we have to make sure that we add inverse patterns for these
-/// folders. This would essentially result in:
-/// ```gitignore
-/// *                     ← ignore everything
-/// !/ba*/                ← except for the `ba*/` pattern, so we scan these folders
