Inline comments:
In `@frontend/src/app/shared/browse/bulk-actions/bulk-actions-bar.component.ts`:
- Line 149: Update the bulk-actions bar capacity calculation around the capacity
expression to reserve space for the projected trailing content: wrap the
trailing slot, access it via viewChild, observe its size, and subtract its
measured width alongside the leading control width before determining overflow.
In `@frontend/src/app/shared/browse/facets.ts`:
- Line 109: Update withBrowseFacetRange’s use of clamp so negative range bounds
accepted by parseRangeToken remain unchanged when formatted; remove the
unconditional lower-bound normalization, or replace it with facet-specific
normalization if one already exists.
In `@frontend/src/app/shared/browse/filter-rail/facet-range-inputs.component.ts`:
- Around line 125-128: Update onUnitChange to convert drafts[side] from its
previous picked unit to the newly selected unit before updating pickedUnits, so
pending fromBox processing preserves the entered value’s meaning; add a test
covering edit followed by a unit change before debounce completion.
In `@frontend/src/app/shared/browse/filter-rail/filter-rail.component.ts`:
- Line 6: Update the `@Component` definitions in
frontend/src/app/shared/browse/filter-rail/filter-rail.component.ts (lines 6-6),
frontend/src/app/shared/browse/filter-rail/filter-section.component.ts (lines
25-25), and frontend/src/app/shared/browse/grid/grid-item.component.ts (lines
8-8) to set changeDetection to ChangeDetectionStrategy.OnPush, importing
ChangeDetectionStrategy from `@angular/core` in each file.
In `@frontend/src/app/shared/browse/filter-rail/filter-section.component.ts`:
- Line 104: Update BrowseFilterSectionComponent.onExpandToggle() to remove the
direct ElementRef.nativeElement.scrollIntoView() call. Encapsulate scrolling in
an existing or new Angular directive or scrolling service, and invoke it from
the component while preserving the {block: 'nearest'} behavior.
In `@frontend/src/app/shared/browse/results.ts`:
- Line 91: Update showAfterCovers() to reset the stored range from
onRenderedRange() before calling deps.artworkUrls(), ensuring a changed list
starts preloading from its initial visible range rather than the previous list’s
deep range. Add a regression test covering a deep rendered range followed by
switching to a cached list.
In `@frontend/src/app/shared/browse/search-input/search-input.component.ts`:
- Around line 41-43: Update the ariaLabel and clearLabel inputs in the
search-input component to be required, ensuring consumers must provide localized
Transloco values; leave the optional placeholder input unchanged.
In `@frontend/src/app/shared/browse/selection-shortcuts.ts`:
- Around line 24-25: Update installBrowseSelectionShortcuts to inject Angular’s
DOCUMENT and Renderer2, then register both document listeners through
Renderer2.listen instead of document.addEventListener. Pass each returned
cleanup function to DestroyRef.onDestroy, preserving the existing listener
callbacks and behavior.
In `@frontend/src/app/shared/browse/selection.ts`:
- Around line 60-63: Update the anchor linkedSignal to derive its reset source
from both deps.listKey and deps.filtersKey, ensuring filter changes reset the
range anchor even when the list key is unchanged. Add a test covering a
filtersKey change followed by a shift-click and verify that no stale anchor
range is selected.
In `@frontend/src/app/shared/ui/number-input/app-number-input.component.ts`:
- Around line 57-58: Update the clear button in AppNumberInputComponent to
remove the tabindex and aria-hidden attributes so keyboard and assistive
technology users can access it, and add a localized accessible name using the
existing Transloco pattern.
In `@frontend/src/app/shared/util/frames.ts`:
- Around line 1-8: Update runOnNextTwoFrames to return a cancellation handle
that prevents both scheduled callbacks from running after cancellation,
including the nested second requestAnimationFrame. At the
BrowseGridViewportComponent and createVirtualGrid call sites, register that
handle with the owning DestroyRef so destruction cancels admissionFrame and
restoreScrollPosition work before stale scrollToOffset or measure calls occur.
In `@frontend/src/app/shared/util/virtual-grid.util.ts`:
- Around line 216-221: Initialize latestWidth from
getScrollContentWidth(measuredElement) before the first emit or ResizeObserver
delivery in the measuredElement setup, so onWindowResize and the initial
gridColumns/lanes calculation use the measured width immediately while
preserving subsequent observer updates.

Learning: In this Angular frontend (under frontend/src/app/), flag manual resource management/cleanup patterns when there is an Angular v16+ automatic alternative. Examples to prefer: (1) Instead of manually pairing document/window event listeners with stored cleanup functions (e.g., add/removeEventListener with mouseMoveCleanup/documentClickCleanup/keydownCleanup/touchCleanup fields), register teardown via DestroyRef.onDestroy(cleanupFn) (or equivalent Angular v16+ teardown mechanism). (2) Instead of storing Subscriptions in fields and explicitly unsubscribing in ngOnDestroy (e.g., annotationSaveSubscription/annotationCacheSubscription), use takeUntilDestroyed(destroyRef) (piped into the observable) or other Angular v16+ primitives. (3) If teardown is lifecycle-coupled and can be automated via DestroyRef/takeUntilDestroyed/signals (or other Angular v16+ mechanisms), prefer the automated approach over manual ngOnDestroy cleanup.

Learning: When reviewing code in the Grimmory frontend (Angular), prefer modern Angular patterns. Specifically: (1) Prefer `DestroyRef` with `takeUntilDestroyed(destroyRef)` for teardown in Angular v16+ instead of manually tracking `Subscription` arrays and calling `unsubscribe()` in `ngOnDestroy()`. (2) Prefer `inject()` for dependency injection over constructor injection where appropriate. (3) Prefer Angular signals (e.g., `signal`, `computed`) over `BehaviorSubject`/`Observable` for state where signals/computed values fit the use case. Flag older patterns when they can be replaced with these modern equivalents without changing behavior.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Convert an existing draft when the unit changes.
drafts[side] uses the unit active during editing. This method changes pickedUnits without converting that draft. The pending timer then calls fromBox with the new unit.
For example, entering 500 and changing from MB to GB before the debounce expires commits 500 GB instead of preserving 500 MB. Convert the draft through its previous unit when the user selects a new unit. Add a test for edit-then-unit-change ordering.

Description
These are the core building blocks of the new browse pages, under
shared/browse. This includes the virtual grid and how it handles loading/positioning, the connection to the Tanstack infinite query for cursor pagination (whether that’s books, series or authors in the future), select and select all behaviour, plus facet, and sort helpers. New components include the filter sidebar, the active filter chips, and the bulk actions bar.None of these are intended to be book-specific, in the future with author/series paginated endpoints these should be entirely shared. The book browser in #2573 will be the first user.

Changes
Grid:
grid.component.ts,grid-viewport.components.ts,grid-item.component.tsandgrid.directives.ts. These make up the basics of the card grid view, with cursor pagination, infinite scroll with specific behaviour for desktop vs mobile, restores scroll position, handles the skeleton/empty/initial error and next-page error states. The page supplies the item, skeleton, and empty templates using the directive, e.g. each of book/author/series will do this.Browse state:
results.ts- This connects the tanstack infinite query to the grid with a flattened item list, status, and next page loading. When filters or sorts change, or an action causes an invalidation, it keeps previous results on screen and preloads covers before changing, so the grid doesn’t flash or go blank.selection.ts+selection-keyboard.ts- Handles multi-select via specific IDs or select-all with the IDs endpoint, or select all + specific manual exclusions. This includes keyboard handling for shift click ranges, escape to clear, CMD/CTRL+A to select all. Changing the sort preserves your selection across the whole paginated output, but changing filters will clear it.search-draft.ts- Debounced search input for the browser’s search. This also includes making the current search visible as an active filter chip alongside other active filters.skeleton-delay.ts- Short delay before skeletons show on first load, so normal / reasonably fast responses don’t flash constantly.facets.ts+facet-ranges.ts- Turns the endpoint facet groups into the filterable groups and items, including order, labels, which are numerical ranges and how to parse the min..max ranges, how values are labelled or given icons. This also freezes the values from the unfiltered facet result so that your list of items doesn’t jump around as the facet counts change.sort.ts- Handles the sort options from the endpoint’s sort tokens, including label, group, default direction, icon kind.Components:
filter-rail- The filter sidebar, including collapsible groups that show counts, per-category search box, show all/fewer for long groups, min/max input boxes for ranges.filter-chips- A bar of active filters or search items using app-tag components, plus a “Clear all filters” button.bulk-actions- The bulk action bar, plus the mobile select toggle. This includes count, select all, clear, and an overflow menu. It doesn’t include any actual buttons, each page can project its own where needed (Book, author, series browsers; series detail or author detail pages).Covers:
cover-components.ts,artwork-revealloaded-artwork-keys.ts- These allow covers to fade in on load as a group. Already-loaded artwork is remembered so revisits don’t fade.Other:
virtual-grid.util.ts- This is now more generic for use with the new browser.frames.ts- Extracted from the virtual grid util so it can be used with the grid viewport component and virtual table view.held-signal.ts- Small signal used to make sure the book cards and active filter components update at the same time as the page update, not before. e.g. when you change a filter or search.app-number-inputcomponent with a clear and stepper input, for the filter’s numeric range inputs (Page count, metadata score, published year etc).grid-density.util.ts- makes public so the shared grid viewport can use the density utility and + / - buttons.flattenBooksPagetobrowse-response.tsand renamedflattenBrowsePage- to be shared for any cursor page responses.tailwind.csssecondary text colour token to a more contrasty shade - used for the filter sidebar component for readability.Manual Testing Steps
Test these on #2575 which includes the book browser, which is the first user of these shared browse pieces.
