The inline date headers can't use CSS position: sticky because
TanStack Virtual positions every item with transform translateY,
which removes them from the document flow.
Workaround: render a separate overlay above the scroll container
that's absolutely positioned (left/right/top: 0) and updates its
label as the user scrolls. The current label is computed from a
pre-built headerOffsets array (cumulative sum of item heights up
to each header) — find the latest header whose offset <= scrollTop,
and that's the group containing whatever's at the top of the view.
The overlay sits at z-20 above the photos with bg-bg/90 +
backdrop-blur and pointer-events-none so it doesn't intercept
clicks. Inline headers still render so the visual flow at group
boundaries is smooth — the overlay is the persistent label.

Two related changes:
1. Sorting controls
- filterStore gains sortBy (taken_at | added_at | filename | file_size
| rating) and sortOrder (asc | desc), defaults taken_at desc.
- filtersToParams sends sort + order to the backend list endpoint.
- usePhotosQuery drops the hardcoded sort/order and reads from the
store.
- useFilterUrlSync round-trips ?sort= and ?order= so the choice
persists in the URL.
- FilterBar gets a Sort group with a field <select> and an asc/desc
toggle button (ArrowDown / ArrowUp icons).
2. Date-grouped timeline (Google Photos style)
- When sorted by a date field (taken_at or added_at), the Timeline
now groups photos by month label ("April 2026") with a small
header row between groups.
- Refactored the virtualizer items from "rows of photos" to a flat
mixed array of header | row items, with per-item heights via the
virtualizer's estimateSize callback. Headers are 36px, photo rows
are THUMBNAIL_SIZE + GAP.
- buildItems() walks photos in order, breaks groups when the month
label changes, and chunks each group into rows of `columns` cells.
Photos with no taken_at fall back to "Unknown date".
- For non-date sorts (filename / file_size / rating) the timeline
reverts to a single un-headered stream — grouping by month
wouldn't be meaningful.
- Range selection and arrow-key nav still operate on the flat
photos array, so grouping is purely a visual layer.
- Also fixes a small bug: photo nav arrow-key handler now ignores
events fired while focus is in an INPUT or TEXTAREA.
Sticky header overlay (the header that stays at the top while you
scroll past photos in its group) is intentionally deferred — inline
headers already give the visual grouping; the sticky behaviour is
polish for a follow-up.

Pick and add-to-heap were two ways of saying "I want to keep this
one". Merging them: P now toggles the selection's membership in the
active heap. The is_picked flag goes away (orphaned in the DB the
same way is_trashed was).
Backend
- Drop is_picked from PhotoBase / PhotoUpdate / PhotoResponse and
from the photos list filter param.
- Drop the is_picked Column from the Photo model (DB column stays
on legacy installs but is no longer read or written).
- Drop the bulk action 'pick' branch.
- New GET /heaps/{id}/photo_ids returns just the flat string list.
Used by the frontend for fast client-side membership lookups
without fetching full photo records.
Frontend
- New hooks/useActiveHeapMembersQuery.ts → returns
{ activeHeap, memberIds: Set<string> }. Subscribes once at the
Timeline level and passes a derived isInActiveHeap bool down to
each PhotoThumbnail (avoids hundreds of thumbnails subscribing
to the same query).
- PhotoThumbnail: replaces the old check-icon Pick affordance with
a clear basket badge in the bottom-right corner — a small filled
pick-colour pill containing a ShoppingBasket icon — visible only
when the photo belongs to the active heap.
- P shortcut (useKeyboardShortcuts) now toggles membership: if every
selected photo is already a member, it removes them; otherwise it
adds the missing ones. T binding removed (P fully replaces it).
- RightSidebar Pick button is now a Pick / Picked toggle bound to
the active heap. Disabled with a hint when no heap is active.
Shows the heap name in its title attr.
- filterStore drops 'picked' and 'unflagged' from FlagFilter.
FilterBar's flag dropdown is now just Any / Discarded.
- LeftSidebar drops the "Flagged" virtual node (it just set
flag=picked, which no longer exists).
- KeyboardHints: P → "Pick → heap".
- Photo TS type drops is_picked.

The loupe view is now called "preview" everywhere — file paths, type
names, store actions, and the contextual hint pill. There's a single
preview action bound to E and Space (Enter is gone); double-click on a
thumbnail still works. Both shortcuts toggle: open from grid, close
from preview.
This commit also folds in the fix for the "preview shows nothing" bug
the user just hit:
- Extract usePhotosQuery into frontend/src/hooks/usePhotosQuery.ts so
Timeline, PreviewView, and App.tsx all share one query — and one
cache entry. Previously PreviewView and App.tsx looked the cache up
by ['photos'], but the Timeline query key gained the filter params
(['photos', filterParams]) when the filter bar shipped, so the
lookup returned undefined and the preview rendered "No photo to
display". App.tsx's getFirstPhotoId callback had the same bug.
- Harden PreviewImage: render the <img> immediately and overlay the
spinner with absolute positioning, instead of toggling opacity-0 →
opacity-100 on load. The previous opacity-toggle could leave the
image stuck invisible if the load event raced with a key change.
- Add { preventDefault: true } to every useHotkeys call so single
letter shortcuts (1-5, P, X, U) no longer leak into Firefox quick-
find, and Cmd/Ctrl+F no longer triggers the browser find toolbar.
Files renamed:
components/loupe/LoupeView.tsx -> components/preview/PreviewView.tsx
components/loupe/LoupeImage.tsx -> components/preview/PreviewImage.tsx
components/loupe/LoupeFilmstrip.tsx -> components/preview/PreviewFilmstrip.tsx
components/loupe/loupeSrc.ts -> components/preview/previewSrc.ts
Symbol renames: openLoupe→openPreview, closeLoupe→closePreview, the
viewMode 'loupe' tag → 'preview', and all the LoupeXxx component and
helper exports.

Adds the spec §6.7 filter bar to the top of the timeline with:
- Date range (native date inputs)
- Media type chips (Photo / Video / RAW / HEIC, multi-select)
- Min star rating (click to set, click again to clear)
- Color label dots (red/orange/yellow/green/blue/purple, single)
- Flag (any / picked / rejected / unflagged)
- Clear-all button
Active filters surface as removable chips below the bar so they're
visible whether the bar is collapsed or open. The TopBar search input
is now wired to the same filter store with a 300ms debounce, and shows
a clear button when populated.
Filter state is the source of truth in a Zustand store and round-trips
through the URL via history.replaceState — bookmarkable and shareable
per spec §6.7. Hydrate happens once on mount; subsequent store changes
write back to ?q=&date_from=&… without navigation.
Timeline reads filter state, builds the backend params via
filtersToParams, and includes them in the React Query key so the cache
invalidates on every filter change. Also fixes a latent bug: Timeline
was sending limit=1000&offset=0, which the backend silently ignores —
swapped to page=1&per_page=500 with explicit sort=taken_at&order=desc.
New keyboard shortcuts:
- \\ toggles the filter bar
- / focuses the TopBar search input
- Cmd/Ctrl+F same as /
Filter button in the TopBar now lights up when filters are active or
the bar is open.

Adds the Lightroom-style full-screen single-photo viewer (spec §6.11).
Open with E / Enter / double-click; navigate with arrow keys; Esc returns
to grid. Filmstrip at the bottom auto-scrolls the active cell into view.
Display:
- Stills source from /photos/{id}/proxy so RAW/HEIC are decoded server-
side; large thumbnail is the onError fallback only.
- Videos render in a <video controls> sourced from /original.
- Continuous wheel zoom (1×–8×, ~15% per tick) with click-drag pan when
zoomed past fit. Z toggles between fit and natural-resolution
(computed from naturalWidth / clientWidth); a second Z snaps back.
- Live percentage indicator in the bottom-center while zoomed.
Polish:
- Neighbor preloading via new Image() when currentIndex changes so arrow
nav feels instant (skips videos).
- Focus trap with role=dialog, aria-modal, focus-on-mount, restore-on-
unmount, and Tab cycling among focusable children.
Plumbing:
- New canonical Photo TS interface in types/photo.ts; removes the three
duplicated definitions in PhotoThumbnail/Timeline/photoStore.
- photoStore gains viewMode + openLoupe/closeLoupe.
- useKeyboardShortcuts wires E/Enter/G to open/close, gates rating and
flag stubs with { enabled: viewMode === 'grid' } so they're inert in
loupe.
- App.tsx mounts <LoupeView/> as a z-40 overlay covering TopBar, gates
the auto-open right sidebar effect on viewMode === 'grid' so leaving
loupe doesn't fight the user's prior sidebar state.
- PhotoThumbnail gains an onDoubleClick prop wired to openLoupe.
