 ## [2.3.0] - 2026-02-04
 
-### Fixed
-
-- **YAML injection in article creation**: `SanitizeForYAML()` now escapes backslashes and newlines; frontmatter templates pass title, description, and author through sanitization
-- **Destructive static export**: Replaced `os.RemoveAll` with safe directory swap pattern (export to `.tmp`, rename on success, preserve original on failure)
-- **Cache race condition**: Counter increments (`hits`, `misses`) now use `atomic.AddInt64` instead of mutating under `RLock`
-- **Cache goroutine leak**: Cleanup goroutine now stops cleanly via `stopCh` channel, signaled by `Shutdown()`
-
 ### Added
 
-- **Article repository tests** (`internal/services/article/repository_test.go`): LoadAll, GetBySlug, GetByTag, GetByCategory, slug generation, reading time
-- **Search service tests** (`internal/services/article/search_test.go`): Basic search, scoring, filters, suggestions, stop words
-- **Cache coordinator tests** (`internal/services/article/cache_test.go`): CRUD, concurrent access with race detector, shutdown cleanup
-- **Content processor tests** (`internal/services/article/content_test.go`): Markdown processing, excerpts, duplicate titles, image/link extraction
-- **CI lint step**: golangci-lint now runs in CI with `only-new-issues: true`
+- **BLOG_TAGLINE config**: Concise navbar branding separate from full blog description
+- **Mobile-first CSS architecture**: Complete design system with CSS custom properties, breakpoints at 481px/769px/1025px
+- **Theme system**: Independent light/dark mode toggle and color presets (default, ocean, forest, sunset, berry)
+- **FOUC prevention**: Inline script in `<head>` reads localStorage before render
+- **Article repository tests** (`repository_test.go`): LoadAll, GetBySlug, GetByTag, GetByCategory, slug generation, reading time
+- **Search service tests** (`search_test.go`): Basic search, scoring, filters, suggestions, stop words
+- **Cache coordinator tests** (`cache_test.go`): CRUD, concurrent access with race detector, shutdown cleanup
+- **Content processor tests** (`content_test.go`): Markdown processing, excerpts, duplicate titles, image/link extraction
+- **CI lint step**: golangci-lint in CI with `only-new-issues: true`
 - **CI coverage threshold**: Build fails if coverage drops below 45%
 
 ### Changed
 
+- **Unified color palette**: Replaced amber accent and rainbow gradients with restrained monochrome system — accent is now a lighter variant of each theme's primary hue
+- **About page sidebar**: 6 hardcoded gradient cards reduced to 1 accent (profile) + 5 neutral cards with borders
+- **Social share buttons**: Platform-specific brand colors replaced with `var(--color-primary)` for consistency
+- **Tech icons**: Individual brand colors standardized to `var(--color-primary-dark)`
+- **Tag cloud**: Filled blue pills changed to outlined style matching article card tags
+- **JS showMessage**: Hardcoded hex colors replaced with CSS custom property reads (with fallback values)
+- **comments.css**: Aligned to project design token system
 - **golangci-lint v1 to v2 migration**: Config schema updated to v2 format, action upgraded to v7 with golangci-lint v2.8.0
 - **quic-go updated** to v0.57.0 (resolves CVE)
-- **GitHub Actions pinned**: `softprops/action-gh-release` pinned to SHA `a06a81a03ee405af7f2048a818ed3f03bbf83c7b`
-- **Documentation accuracy**: Fixed broken links, stale coverage numbers, nonexistent Makefile targets, wrong PORT defaults, and obsolete binary references across all docs
