Click on the For-You tile's play button now triggers a synchronous
refresh, then enqueues + auto-plays the freshly-built playlist.
Two-click-target tile pattern: tile BODY click still navigates to
the playlist detail page (existing behavior); the play button is
the new generate-and-play action.
Behavior is gated on playlist.system_variant === 'for_you' — every
other playlist (user, Discover, Songs-like-X) keeps the existing
"fetch detail, enqueue, play" flow. The atomic-replace BuildSystem-
Playlists creates a new playlist_id, so the play handler uses the
refresh response's id for the follow-up getPlaylist call rather
than the stale tile prop's id.
Empty-library response (playlist_id: null) is a no-op — clicking
play in a degenerate-empty library doesn't error, it just doesn't
start playback. Caches are invalidated post-refresh so the home
view re-fetches and the tile re-renders with the new id, avoiding
the corner case of a click-then-tile-body 404.
Tests cover the refresh-and-play happy path, the empty-library
no-op, and that non-For-You playlists keep the existing flow.

Operator can refresh their Discover playlist without waiting for
the next daily cron tick. Two surfaces, both gated on
system_variant === 'discover':
- Detail page header: "Refresh" button next to the cover art / meta.
- Home Playlists row tile kebab: "Refresh Discover" menu item.
Both call POST /api/playlists/system/discover/refresh, show a
confirmation toast, and invalidate the playlist + playlists queries
so the new content lands without a manual page reload.
Extends Playlist.system_variant union with 'discover'. Adds
refreshDiscover() typed client. Tests cover client behaviour
(success + empty-library) plus conditional rendering on both
surfaces.
The <img alt=""> production element renders as role="presentation"
(decorative — playlist name is in sibling text). screen.getByRole('img')
doesn't match presentation-role elements. Switch to
container.querySelector('img') so the test doesn't fight the
correct a11y choice. Production code unchanged.
Square card with cover (or "No tracks yet" glyph fallback), name,
track count, and owner attribution when the playlist isn't the
current user's. Click navigates to /playlists/{id}.
