## What
Adds a **Storybook preview** for PRs. When a PR changes any story
(`*.stories.{ts,tsx,mdx}`) or the `.storybook` config, this builds the
static Storybook, deploys it to the preview VPS on a PR-scoped port, and
comments with the URL plus an **expandable list of exactly which stories
changed**. Torn down automatically when the PR closes.
New file: `.github/workflows/storybook-preview.yml`. Nothing else is
touched.
## How
- **Detect** (`changes` job) - `dorny/paths-filter` with `list-files:
json` flags Storybook changes and captures the exact changed files.
Skipped on close and for fork PRs (which don't get the VPS secrets).
- **Deploy** (`deploy` job, only when Storybook changed) - builds the
static Storybook (`task frontend:prepare` + `frontend:storybook:build`),
tars it, and serves it from an `nginx:alpine` container on the VPS at
port `PR# + 20000` (offset from the app preview's bare-PR-number port to
avoid collisions). Mirrors `PR-Auto-Deploy-V2.yml`'s VPS SSH pattern and
reuses the same secrets.
- **Comment** - a single bot comment (replaced on each push) with the
preview URL and a `<details>` block listing the changed stories (and any
`.storybook` config changes), e.g.:
> ## 📚 Storybook preview
> 🔗 **Preview:** http://<vps>:26911
> <details><summary>2 stories changed (+1 config
file)</summary>…</details>
- **Cleanup** (`cleanup` job, on PR close) - stops the container,
removes the files, and deletes the comment.
## Validation
- Static Storybook builds locally (`task frontend:storybook:build` →
`frontend/storybook-static`, 151 stories).
- Confirmed `task frontend:prepare` regenerates the un-committed
`material-symbols-icons.json` that stories import, so a fresh CI
checkout builds (added it before the build step).
- Comment-markdown logic unit-checked against a sample changed-files
list.
- YAML validated; action pins match the repo (`setup-node` v6.4.0 / node
22, same `paths-filter`, `setup-bot`, `harden-runner`).
## Note
The VPS deploy mirrors the proven `PR-Auto-Deploy-V2` machinery but
couldn't be exercised end-to-end from a dev box (needs the VPS secrets)
- the first live run on a Storybook-touching PR will confirm the
deploy/serve/cleanup path. Everything build- and comment-side is
validated locally.
