v0.1.21

## ✨ Highlights

- **🎬 Smooth 60 fps, styleable videos** — `video-start --fps=60` records smooth 60 fps videos instead of the default 25, and `video-start --cursor` renders an animated mouse cursor that travels to each action point and stays visible between actions. `video-show-actions` takes `--point-style`, `--highlight-style` and `--title-style` CSS declarations; the action point marker and the target highlight are now only shown when styled. ([microsoft/playwright#42752](https://github.com/microsoft/playwright/pull/42752), [microsoft/playwright#42758](https://github.com/microsoft/playwright/pull/42758))
- **🧰 WebMCP tools show up in the snapshot** — the tools a page registers are listed at the top of the page snapshot with their descriptions and input schemas, so `webmcp-call` can be used without running `webmcp-list` first. Set `webmcp: false` in the config file (env `PLAYWRIGHT_MCP_WEBMCP=false`) to stop collecting page-registered tools. ([microsoft/playwright#42671](https://github.com/microsoft/playwright/pull/42671))
- **🌗 Switch between light and dark color scheme** ([microsoft/playwright#42243](https://github.com/microsoft/playwright/issues/42243)) — an agent working on a dark theme had no way to see it mid-session. New `set-color-scheme`, `set-reduced-motion`, `set-forced-colors`, `set-contrast` and `set-media` commands emulate media features on the fly, and the matching `clear-*` commands reset them. ([microsoft/playwright#42668](https://github.com/microsoft/playwright/pull/42668))
- **📁 Absolute paths in results** ([microsoft/playwright#42497](https://github.com/microsoft/playwright/issues/42497)) — links to snapshots, screenshots, console logs and downloads are relative to the working directory, which a consumer without one cannot resolve. Set `filePaths: "absolute"` in the config file (env `PLAYWRIGHT_MCP_FILE_PATHS=absolute`) to get absolute paths instead. ([microsoft/playwright#42673](https://github.com/microsoft/playwright/pull/42673))

## 🐛 Fixes

- `fix(chromium): bypass service workers on the storage state page` — `state-save` no longer runs the site's own scripts, or fails when they redirect, for origins with an active service worker ([microsoft/playwright#42656](https://github.com/microsoft/playwright/issues/42656)). ([#42664](https://github.com/microsoft/playwright/pull/42664), [#42741](https://github.com/microsoft/playwright/pull/42741))
- `fix(mcp): keep upload modal, skip short secrets and bad headers` — a failed `upload` keeps the file chooser open so it can be retried, secrets shorter than 4 characters no longer rewrite the whole output with `<secret>` markers, and `route` ignores header lines that have no name. ([#42713](https://github.com/microsoft/playwright/pull/42713))
