- Use existing MULTIPLIER_S/M/L from \$entities/Font in SliderArea instead
of inlining the 0.5/0.75/1 literals (constants already existed but were
duplicated at the call site).
- Centralize API base URL in \$shared/api/endpoints.ts (was duplicated
between proxyFonts and FilterAndSortFonts filters api).
- Promote every 'glyphdiff:...' localStorage key to a named module-level
STORAGE_KEY constant. Test files now import the source constant rather
than redeclaring it (eliminates silent-typo divergence risk).
Structural:
- Merge factory + singleton from lib/settingsManager and model/state into
one model/store/typographySettingsStore/ slice
- Drop now-empty lib/ and model/state/ directories
Semantic:
- Rename feature SetupFont -> AdjustTypography (the feature owns
continuous typography adjustment, not one-time font setup)
- Drop "Manager" from TypographySettingsManager -> TypographySettingsStore
(class + factory); singleton typographySettingsStore unchanged
All consumers (Character, Line, SampleList, SliderArea, FontSampler,
comparisonStore) updated. Public barrel signature changed: now exports
createTypographySettingsStore and type TypographySettingsStore.
