Walkthrough

EmptyGalleryState now supports custom actions. AlbumDetail uses it for empty albums, preserves the Add Images action, and adjusts header and photo-count alignment.

Changes

Album empty-state integration

Layer / File(s)	Summary
Custom empty gallery action frontend/src/components/EmptyStates/EmptyGalleryState.tsx	EmptyGalleryState accepts an optional action React node. The default Settings prompt remains when no action is provided. The formats hint renders only when supplied.
Album detail layout and empty state frontend/src/pages/Album/AlbumDetail.tsx	The album header uses separate aligned sections. Photo counts appear below the controls. Empty albums use EmptyGalleryState with the existing Add Images button.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to c5ce3

This change centers the Add Images action in the empty album view, with no actionable merge-blocking risk remaining beyond normal UI review and checks.

Poem

I’m a rabbit with a tidy view,
Empty albums now know what to do.
Add Images sits just right,
Counts align in clean delight,
And settings wait when actions are few.

235-250: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the album header responsive on narrow screens.

The outer header uses a single-row flex layout at every viewport width. The title block and action column can compress or overflow on narrow screens. This can make Add Images and selection controls difficult to use. Stack the sections on small screens and switch to a row at a larger breakpoint. Also allow the action row to wrap.

As per path instructions, frontend code must follow responsive design principles.

Proposed layout adjustment

-      <div className="mb-6 flex items-start justify-between gap-4">
+      <div className="mb-6 flex flex-col gap-4 sm:flex-row sm:items-start sm:justify-between">
...
-        <div className="flex flex-col items-end gap-2">
+        <div className="flex flex-col items-start gap-2 sm:items-end">

Add a regression test for the empty-album action.

When images.length === 0, verify the empty-state title and description, verify that the formats hint is hidden, and verify that clicking Add Images opens AddImagesToAlbumDialog. This protects the new EmptyGalleryState action contract and the empty-album flow.

As per path instructions, critical functionality must have automated test coverage.
