Subject: [PATCH 2/5] Add Playwright, rsvg-convert, and Node.js checks to test
 setup

The test configuration scripts now include:

- Node.js version check (warns if < 18 for Playwright compatibility)
- Playwright setup with browser installation and multiplex server dependencies
- rsvg-convert checks for SVG to PDF conversion tests
- Switch from yarn to npm for consistency between local setup and CI

The Playwright setup uses npm install and includes both main Playwright dependencies and multiplex server dependencies required by integration tests

Subject: [PATCH 3/5] tests: Document optional dependencies checked by
 configure scripts

Add section to tests/README.md documenting the optional test dependencies
that configure-test-env scripts check for and install:
- Java (for veraPDF)
- Node.js and npm (for Playwright and MECA validation)
- pdftotext (for PDF text extraction)
- rsvg-convert (for SVG to PDF conversion)

Documents installation instructions for each platform and notes about
auto-installation via Scoop on Windows.

 variables

- Add PowerShell version of run-fast-tests for Windows
- Add --keep-outputs/-k flag to run-tests.ps1 (matches bash version from ed683a345)
- Document run-fast-tests.sh environment variables with detailed comments
- Add comprehensive test environment variables section to README.md

Environment variables documented:
- QUARTO_TESTS_NO_CONFIG - Skip configure-test-env
- QUARTO_TESTS_FORCE_NO_VENV - Skip .venv activation
- QUARTO_TEST_KEEP_OUTPUTS - Keep test artifacts (new flag support in PS1)
- QUARTO_TEST_VERBOSE - Verbose output
- QUARTO_TESTS_NO_CHECK - Legacy/unused variable

Changes bring feature parity between bash and PowerShell test runners.

 ```
 
+**Quick test runs with run-fast-tests scripts**
+
+For convenience, `run-fast-tests.sh` and `run-fast-tests.ps1` are provided to skip environment configuration:
+
+```bash
+# Linux/macOS
+./run-fast-tests.sh
+
+# Windows
+./run-fast-tests.ps1
+```
+
+These scripts set `QUARTO_TESTS_NO_CONFIG` automatically. Use after running `configure-test-env` at least once.
+
+**QUARTO_TEST_KEEP_OUTPUTS** (or use `--keep-outputs`/`-k` flag)
+- Keep test output artifacts instead of cleaning them up
+- Useful for debugging test failures or inspecting generated files
+- Can be set via environment variable or command-line flag
+
+```bash
+# Using flag
+./run-tests.sh --keep-outputs
+./run-tests.sh -k
+
+# Using environment variable
+QUARTO_TEST_KEEP_OUTPUTS="true" ./run-tests.sh
+```
+
+```powershell
+# Using flag
+./run-tests.ps1 --keep-outputs
+./run-tests.ps1 -k
+
+# Using environment variable
+$env:QUARTO_TEST_KEEP_OUTPUTS="true"
+./run-tests.ps1
+```
+
+**Other environment variables**
+- `QUARTO_TEST_VERBOSE` - Enable verbose test output
+- `QUARTO_TESTS_NO_CHECK` - Not currently used (legacy variable)

 #### About smoke-all tests
 
 `docs/smoke-all/` is a specific folder to run some tests written directly within `.qmd`, `.md` or `.ipynb` files (but files starting with `_` will be ignored). They are run through the `smoke/smoke-all.tests.ts` script. To ease running smoke-all tests, `run-tests.sh` has a special behavior where it will run `./smoke/smoke-all.tests.ts` when passed a `.qmd`, `.md` or `.ipynb` file, not starting with `_`.
