- splitArray: replace the comma-operator reduce body with an explicit
block + return (no-sequences); behaviour unchanged
- BreadcrumbHeaderSeeded: declare the bind:this ref with $state() so it
is not flagged as never-assigned (oxlint cannot see template bindings),
matching the rest of the codebase; guard the onMount use
Cleanup surfaced once the oxlint config actually loads (no-unused-vars).
- drop dead locals/imports/params (cachedOffsetTop, elasticOut, key,
unused type imports, unused test imports; _-prefix unused mock params)
- createVirtualizer: keep the _version read (reactive subscription inside
$derived.by) but bind it to _v so it is not flagged
- scrollBreadcrumbsStore.test: keep the removeEventListener mock side
effect, drop the unread spy binding
oxlint was never loading its config: the file was named oxlint.json but
oxlint only auto-discovers .oxlintrc.json/.jsonc, and the `ignore` field
was invalid (should be `ignorePatterns`). So import/no-cycle and every
other rule silently never ran.
- rename oxlint.json -> .oxlintrc.json, fix ignore -> ignorePatterns
- turn off the restriction/style category grab-bags (opt-in, partly
contradictory); enable wanted rules individually
- add overrides enforcing FSD layer direction and the interior
ui -> model -> domain law via no-restricted-imports (oxlint has no
zone rule); import/no-cycle resolves $-aliases via tsconfig discovery
The native Popover always renders its content (the vertical slider), so the
slider's value label is in the DOM even when closed, and opening is driven by
the browser's declarative popovertarget invoker (not simulated by jsdom on
click). Update the tests to scope value assertions to the trigger and drive
open via showPopover(), matching Popover.svelte.test.ts.
Convert the eager layoutManager singleton to getLayoutManager() (+ __resetLayoutManager
for tests), so its persisted layout preference is read on first access rather than at
module load. Update the model barrels and consumers (LayoutSwitch, SampleListSection,
SampleList) with $derived reads; the LayoutSwitch test resolves via the accessor.
Convert the eager fontLifecycleManager singleton to getFontLifecycleManager()
(+ __resetFontLifecycleManager for tests), so its AbortController/FontFace
bookkeeping is set up on first use rather than at module load. Update consumers
(FontVirtualList, FontList, SampleList) and resolve it once as a field in
comparisonStore; the comparisonStore mock now exposes getFontLifecycleManager.
Convert the eager scrollBreadcrumbsStore singleton to getScrollBreadcrumbsStore()
(+ __resetScrollBreadcrumbsStore for tests) and add a public destroy() that
disconnects the IntersectionObserver and scroll listener. Update the feature
barrel and consumers (BreadcrumbHeader, BreadcrumbHeaderSeeded, NavigationWrapper).
Convert the eager typographySettingsStore singleton to getTypographySettingsStore()
(+ __resetTypographySettingsStore for tests) and update barrels and consumers
(TypographyMenu, FontSampler, SampleList, ComparisonView Line/SliderArea,
comparisonStore + its mock).
Fix a latent leak while here: the store ran $effect.root and discarded the
returned cleanup, so its storage-sync effects outlived every instance. Capture
the disposer and expose destroy(), which __reset now calls.
Convert the eager themeManager singleton to a getThemeManager() lazy accessor
(+ __resetThemeManager for tests), so the persistent-store subscription is set
up on first access rather than at module load. Update the barrel and consumers
(Layout init/destroy, ThemeSwitch, story, test).
Convert appliedFilterStore, availableFilterStore and sortStore from eager
module-level singletons to getAppliedFilterStore/getAvailableFilterStore/
getSortStore lazy accessors (+ __reset* helpers for tests), so the
availableFilterStore QueryObserver is built on first use rather than at import.
Update barrels, the startFilterBindings bridge, and all consumers. Reactive
reads in components are wrapped in $derived; two-way bind:value targets resolve
the accessor once and bind directly (a $derived is read-only).
Replace the side-effect-on-import $effect.root in bindings with an explicit
startFilterBindings() started from an AppBindings provider in onMount, so the
filters/sort -> font-catalog bridge has a lifecycle tied to the app tree and a
returned cleanup. bindings now consumes getFontCatalog().
Fix the effect-update loop this surfaced: setGroups populated the reactive
groups array in place via `groups.length = 0; groups.push(...)`. push reads the
array's length signal, so the populating effect both read and wrote
groups.length each run and re-triggered itself forever
(effect_update_depth_exceeded). setGroups now reassigns the array (groups is
`let`), which does not read length.
Extract mapFilterMetadataToGroups to own the metadata -> group-config mapping,
including sorting a copy of options (the source is TanStack-cached data; an
in-place sort corrupts the cache and writes into the effect's read dependency).
Mirror the font-catalog change in ComparisonView: expose getComparisonStore()
(plus __resetComparisonStore for tests) instead of an eager comparisonStore
singleton, and consume getFontCatalog() internally. Update the model barrel and
all UI consumers (Sidebar, FontList, Header, Line, SliderArea); Character no
longer needs the store and reads everything from props.
Update both specs to the accessor: comparisonStore.test mocks getFontCatalog
with a writable stub (the real store's fonts is getter-only) and resets the
catalog between cases; Sidebar.svelte.test resolves the store via the accessor.
Also document Character's props.
Swap the eagerly-constructed fontCatalogStore singleton for a lazy
getFontCatalog() accessor (plus __resetFontCatalog for tests), so the
InfiniteQueryObserver is created on first use rather than at module load.
Update the model barrels and all consumers (FontVirtualList, SampleList,
SampleListSection) to the accessor.
Also extract createFontLoadRequestConfig from FontVirtualList: it resolves a
font's URL for a weight and returns a 0-or-1 element array, letting callers
flatMap over a list to build load requests and drop unresolvable fonts in one
pass.
FontApplicator and FontSampler no longer read fontLifecycleManager. They take a
`status` prop (FontLoadStatus | undefined) supplied by the composing widget;
FontList and SampleList resolve status once per visible row and pass it down.
FSD+ dependency inversion: the entity/feature UI depends on a value, not the
lifecycle store. Removes FontApplicator's value-import of the store (one step
toward an inert ./ui barrel) and drops the duplicate getFontStatus read per row
in FontList. FontSampler is now status-decoupled and trivially relocatable to
entities/Font/ui.
Extract NonRetryableError into its own tanstack-free module and drop the
./api re-export from the Font slice barrel. Importing $entities/Font no
longer transitively loads @tanstack/query-core or constructs the QueryClient
singleton via the ./api and ./lib (errors) chains — light consumers (domain,
types, consts) and unit specs stop paying for TanStack.
Note: ./ui still pulls the stores; addressed separately.
The body font-family referenced "Karla", which was never loaded, so
body text silently fell back to system-ui. Point it at the existing
--font-secondary token (Inter + system fallbacks).
Remove the googleapis stylesheet, both google preconnects, and the two
dead fontshare preconnects from the document head. Preload the two
render-critical faces (Inter, Space Grotesk) via Vite ?url imports.
Eliminates two third-party origins and the IP leak to Google.
Replace Google Fonts CDN delivery of the four UI typefaces (Inter,
Space Grotesk, Space Mono, Syne) with latin-subset woff2 vendored into
app/assets/fonts and wired via a hand-authored @font-face stylesheet.
Variable faces keep wght (Inter also opsz). Vite content-hashes the
binaries for immutable caching.
Re-exporting the store singletons (fontCatalogStore, fontLifecycleManager,
FontsByIdsStore) through entities/Font/index.ts meant every consumer of the
barrel eager-instantiated stores and pulled @tanstack/query-core — in dev,
test, and as retained code. Drop the store re-export from the top barrel;
keep the pure surface (types, constants, domain, lib, ui) there for
convenience. Consumers that need stores import $entities/Font/model.
Aligns with the BaseQueryStore carve-out: barrel by default, segment path
when it would drag a heavy or side-effectful dependency.
Without the field, Rollup treats every module as potentially side-effectful
and cannot drop unused re-exports pulled through barrels. Audited all
import-time side effects: only CSS and the two bare side-effect imports
(router.ts, bindings.svelte.ts) must be preserved; module-level store
singletons ride their export usage and need no listing. Trims the bundle
~8 KB raw / ~2.4 KB gzip.
Breadcrumb is not a business aggregate — it is a scroll-tracking navigation
capability (NavigationWrapper registers page sections into a store), so it
belongs in the features layer, not entities. Move the whole slice and
repoint its three widget consumers. entities/ now holds only Font, a true
aggregate.
BaseQueryStore pulls @tanstack/query-core. Re-exporting it through the
broad $shared/lib and $shared/lib/helpers barrels made every consumer of
those barrels eager-load TanStack at module-eval time (no tree-shaking in
vitest/vite-node), which is what surfaced the queryClient mock init-order
failure. Its single consumer now imports it by path.
