Ilia Mashkov 0aae710e35 fix: dispose persistent-store effects; close comparisonStore effect leak
Thread the new createPersistentStore.destroy() through its owners so the
save effect.root is actually torn down: LayoutManager gains destroy();
ThemeManager and typographySettings dispose their #store in their existing
destroy().

comparisonStore had its own leak — a constructor $effect.root whose disposer
was discarded, and a module-level persistent storage created at import. Move
storage into the instance (#storage, created lazily per instance), capture
the effect.root disposer, add destroy(), and adopt createSingleton so reset
runs resetAll() + destroy(). Re-export createSingleton from the $shared/lib
barrel; give the test storage mock a destroy().

GlyphDiff

A modern font exploration and comparison tool for browsing fonts from Google Fonts and Fontshare with real-time visual comparisons, advanced filtering, and customizable typography.

Features

  • Multi-Provider Catalog: Browse fonts from Google Fonts and Fontshare in one place
  • Side-by-Side Comparison: Compare up to 4 fonts simultaneously with customizable text, size, and typography settings
  • Advanced Filtering: Filter by category, provider, character subsets, and weight
  • Virtual Scrolling: Fast, smooth browsing of thousands of fonts
  • Responsive UI: Beautiful interface built with Tailwind CSS
  • Type-Safe: Full TypeScript coverage with strict mode enabled

Tech Stack

  • Framework: Svelte 5 with reactive primitives (runes)
  • Styling: Tailwind CSS v4
  • Components: Bits UI primitives
  • State Management: TanStack Query for async data
  • Architecture: Feature-Sliced Design (FSD)
  • Quality: oxlint (linting), dprint (formatting), lefthook (git hooks)

Code Style

  • Path Aliases: Use $app/, $shared/, $features/, $entities/, $widgets/, $routes/
  • Components: PascalCase (e.g., ComparisonSlider.svelte)
  • Formatting: 100 char line width, 4-space indent, single quotes
  • Type Safety: Strict TypeScript with JSDoc comments for public APIs

Architecture Notes

This project follows the Feature-Sliced Design (FSD) methodology for clean separation of concerns. The application uses Svelte 5's new runes system ($state, $derived, $effect) for reactive state management.
