# Quickstart: Copy URL & Toast Notifications

## Happy Path — Copy URL

1. Open any image detail page (e.g. `http://localhost:4200/images/{id}`).
2. Confirm a "Copy URL" button is visible.
3. Click "Copy URL".
4. Confirm a success toast appears ("URL copied!" or similar) and then disappears automatically.
5. Paste into a text editor — confirm the pasted value is the full image file URL.

## Happy Path — Toast Auto-Dismiss

1. Click "Copy URL".
2. Confirm the toast appears.
3. Do not interact — wait ~3 seconds.
4. Confirm the toast disappears on its own.

## Edge Case — Clipboard Unavailable

1. In Firefox, navigate to `about:config` and set `dom.events.asyncClipboard.clipboardItem` to `false` (or test with a non-HTTPS localhost where clipboard API may be blocked).
2. Click "Copy URL".
3. Confirm an error toast appears (e.g. "Failed to copy URL") and auto-dismisses.

## Edge Case — Rapid Clicks

1. Click "Copy URL" three times quickly.
2. Confirm only one toast is visible at a time (new toast replaces old, no overlapping stack).

## Regression — Other Pages

1. Navigate to the library (`/`), upload page (`/upload`), tags page (`/tags`).
2. Confirm no toast or copy button is visible on these pages.
3. Confirm existing functionality is unaffected.
