+All scripts use the same base URL helper. Default: `http://localhost:8000` (override with `BASE_URL`).
+
+Install k6:
+- Via Homebrew (macOS): `brew install k6`
+- Via Chocolatey (Windows): `choco install k6`
+
+Verify installation:
+```sh
+k6 version
+```
+
+Run locally:
+- `k6 run --env BASE_URL=http://localhost:8000 performance-tests/load.js`
+- `k6 run --env BASE_URL=http://localhost:8000 performance-tests/spike.js`
+- `k6 run --env BASE_URL=http://localhost:8000 performance-tests/stress.js`
+- `k6 run --env BASE_URL=http://localhost:8000 performance-tests/soak.js`
+
+Via Docker (no local k6), PowerShell:
+- `docker run --rm -it --network host -v ${PWD}/performance-tests:/scripts grafana/k6 run --env BASE_URL=http://localhost:8000 /scripts/<file>.js`
+
+Notes:
+- Stress is capped at 150 VU with p95<4s target (matches what backend currently klarer).
+- Spike går til 150 VU med et mere lempeligt p95<6s target.
+- Soak kører 1 time; stop den når du har nok data.
