# Why is the DLR shut today?

A single-page site that displays one randomly chosen message in the centre of
the screen. The message changes on every page load and whenever the
**Check again** button is pressed.

The site is themed around the Docklands Light Railway colour scheme, with a
toggle between:

- **Modern colours** — the current DLR turquoise/teal branding.
- **Original colours** — the 1987 DLR red-and-blue livery.

The chosen theme is remembered between visits via `localStorage`.

## Adding messages

Edit `messages.js` and fill the `MESSAGES` array with your own reasons — one
string per entry. Entries are inserted as plain text. Until you add some, the
page shows a fallback prompt.

## Running

It is a static site with no build step. Open `index.html` in a browser, or
serve the directory with any static file server, for example:

```sh
python3 -m http.server
```
