v2.1.0 — Theme packs, UI polish & themed app icons

What's New

Theme Packs (7 color schemes)

• Material You (system dynamic color, Android 12+)
• Purple (default)
• Ocean Blue
• Forest Green
• Rose Pink
• Sunset Orange
• Teal Mist

Settings → Appearance → Color Theme. Each option shows live color preview swatches.

Themed App Icons

The home-screen icon background now matches your selected theme color. The moon + star foreground stays the same; the background changes. The app restarts when you switch themes (expected — Android requires this to swap launcher icons).

UI Polish

• Gradient hero card on the summary screen
• Color-coded icons: feeding=primary, sleep=tertiary, diaper=secondary
• Card elevation throughout for visual depth
• Gradient bar chart fills
• Icon circles with tinted backgrounds

App Icon

Replaced the default Android Studio smiley face with a crescent moon + star on a night-sky gradient. Clean, minimal, nighttime/calm theme.

Technical

• Zero new dependencies — all theming uses existing Compose Material 3 APIs
• All icons are vector XML (no PNG bloat)
• APK size: 27MB (down from 28MB)
• minSdk 26 (Android 8.0+)
