Long-tail cleanup: threshold and default-value literals in shared
helpers get named module-level constants.
- CharacterComparisonEngine: CHAR_PROXIMITY_RANGE_PCT (5),
DEFAULT_RENDER_SIZE_PX (16) — kept local instead of importing
DEFAULT_FONT_SIZE from \$entities/Font because \$shared/lib cannot
legally upward-import from \$entities per FSD (also avoids an init
cycle through the mocks barrel).
- typographySettingsStore: BASE_SIZE_EPSILON (0.01) — rounding-jitter
guard for baseSize reconciliation.
- createDebouncedState: DEFAULT_DEBOUNCE_MS (300) — exported so callers
can mirror the default.
- createVirtualizer: MEASUREMENT_EPSILON_PX (0.5) — minimum height
delta before committing a re-measured row.
- createPerspectiveManager: PERSPECTIVE_TOGGLE_THRESHOLD (0.5) — the
halfway point on the 0-1 spring that flips isBack/isFront.
Skipped #19 (PerspectivePlan defaults) per review — marginal gain.
Both names were vague or overloaded:
- fontStore / FontStore -> fontCatalogStore / FontCatalogStore
Three font-related stores live in this slice; the new name names the
paginated catalog specifically.
- appliedFontsManager / AppliedFontsManager -> fontLifecycleManager /
FontLifecycleManager
"Applied" collided with the filter-side appliedFilterStore (different
meaning). The class actually orchestrates a load-use-evict lifecycle
with FontBufferCache + FontEvictionPolicy + FontLoadQueue
collaborators, so "Manager" is justified. Companion types file moved
alongside (appliedFonts.ts -> fontLifecycle.ts).
Directories, file basenames, factory (createFontStore ->
createFontCatalogStore), and the AppliedFontsManagerDeps interface all
renamed. All consumers (ComparisonView, SampleList, FontList,
FontApplicator, FontVirtualList, FilterAndSortFonts bindings,
createFontRowSizeResolver, mocks) updated.
