Add fullscreen mood animations with user controls following Material Design 3 Expressive principles

[Copilot]

Adds a fullscreen celebration animation when users select a mood emoji, using the mood's calendar color as the background. Implements refined animations throughout the app following Material Design 3 Expressive principles with consistent motion, color-only transitions, and user controls for animation preferences.

Changes

New Components

• MoodAnimation.razor - Fullscreen overlay with 1s auto-dismiss using unified animation for all emojis
• MoodAnimation.razor.css - Simplified scale animation with special visual effects (rain, sunshine, stars, clouds) per mood and prefers-reduced-motion support

Integration

• DataPointView.razor - Triggers animation on mood selection (excludes "undecided" emoji), merged with motivational quote feature
• Index.razor - Instantiates MoodAnimation component

Enhanced Animations

• wwwroot/app.css - MD3 Expressive animations with color transitions only (press animations removed except calendar days)
• Pages/Index.razor.css - Removed data point slide-in animations, color transitions only
• Pages/Calendar/CalendarDay.razor.css - Calendar day press animations and simplified emoji pop
• Pages/SettingsPage.razor - Added animation controls, improved import/export flow with non-blocking UI
• Pages/SettingsPage.razor.css - Theme color transitions for smooth theme switching

User Controls

• Data/PreferenceService.cs - Added DisableExtraAnimations setting to allow users to turn off emoji celebration animations

Mood Animation

All emojis use the same smooth scale animation for consistency, with unique visual effects:

• 😭 Crying - Falling rain drops (💧) and rain lines effect
• 😢 Sad - Lighter rain effect
• 😕 Confused - Floating clouds (☁️)
• 😐 Neutral - No special effects
• 🙂 Slight smile - Sparkles effect
• 😀 Happy - Sunshine (☀️) with warm glow
• 🤩 Excited - Twinkling stars (⭐)

Material Design 3 Expressive Principles

Animation Controls:

• Users can disable extra animations (emoji celebrations) via Settings → Personalization
• Setting is persisted in preferences

Color-Only Interactions:

• All press/active scale animations removed except calendar days
• Calendar days scale to 0.95 on press (only interactive element with press animation)
• All other elements use color transitions only for state changes
• Smooth 0.2-0.3s transitions on all color changes
• Applied to: backgrounds, borders, buttons, cards, inputs, sliders, toggles, theme switching
• Uses MD3 easing: cubic-bezier(0.2, 0, 0, 1)

Preserved Entrance Animations:

• Page body fade-in
• Card staggered appearances (only cards, not individual data points)
• Calendar days staggered pop-in
• Dialog scale-in (including note creation)
• Snackbar slide-up
• Current day pulse effect

Timing & Easing:

• Emoji animation: 1s with cubic-bezier(0.05, 0.7, 0.1, 1)
• Color transitions: 0.2-0.3s with cubic-bezier(0.2, 0, 0, 1)

Import/Export Improvements

• Loading indicator now renders asynchronously with 100ms delay
• UI remains responsive during background work
• No more frozen screens during import/export operations
• Smooth transition to loading state

Implementation

void OnMoodSelected(string mood)
{
    Point.Mood = mood;
    
    // Skip animation if disabled in settings
    if (MoodAnimation != null && mood != "🤔" && !PreferenceService.DisableExtraAnimations)
    {
        MoodAnimation.Show(mood);
    }
    
    // Show motivational quote for crying emoji
    if (mood == DataPoint.Moods[^1])
    {
        var quote = MotivationalQuotes.GetRandomQuote();
        Snackbar.Add(quote, Severity.Info, c => c.Icon = Icons.Material.Rounded.FavoriteBorder);
    }
}

The animation retrieves colors via PreferenceService.GetMoodColor() to maintain visual consistency with the calendar grid. Animation timing is optimized at 1s for a snappier feel. All animations use CSS transforms and opacity for hardware-accelerated 60fps performance. Respects prefers-reduced-motion for accessibility. Optional parameter design preserves backward compatibility—existing DataPointView usages continue to work without modification.

Original prompt

Add a nice, engaging fullscreen animation after selecting an overall mood emoji. The animation should use the color that's used in the calendar square for that mood

@copilot Use special animations for each one, such as rain for the crying emoji and sunshine for the happy one. There's also a bit of lag at the end where it shows the emoji static for a split second

[danielchalmers]

@copilot experiment with animations for other parts of the app too. it's for a test so don't be reserved! i want to make the app more fluid and fun

@copilot Use special animations for each one, such as rain for the crying emoji and sunshine for the happy one. There's also a bit of lag at the end where it shows the emoji static for a split second

Implemented unique animations for each emoji in commit 34def9b:

Animations:

• 😭 Crying: Shaking motion with falling rain drops (💧) and rain lines
• 😢 Sad: Gentle shake with lighter rain effect
• 😕 Confused: Tilting back and forth with floating clouds (☁️)
• 😐 Neutral: Simple scale animation
• 🙂 Slight smile: Gentle bounce with sparkles
• 😀 Happy: Energetic bounce with sunshine (☀️) and warm glow
• 🤩 Excited: Full 360° spin with twinkling stars (⭐)

Timing fix: Reduced animation duration from 1500ms to 1400ms to eliminate the static emoji lag at the end. The component now hides at exactly the right moment as the fade-out completes.

Added fluid animations throughout the app in commit 100bcfd:

Global animations:

• Page fade-in and slide-down header
• Card staggered appearance with hover elevation
• Button hover lift and click scale
• Icon button rotate and scale effects
• Menu slide-in animations
• Dialog bouncy scale-in
• Snackbar slide-up from bottom
• Loading screen pulse

Calendar animations:

• Days pop in with staggered timing
• Hover scale with shadow elevation
• Current day pulse effect
• Emoji rotation on hover
• Emoji pop animation when added

Timeline animations:

• Data points slide in from left
• Staggered appearance for smooth flow
• Rating stars scale and rotate
• Day switcher buttons translate on click
• Sleep controls rotate on hover
• Toggle buttons bounce

All animations respect prefers-reduced-motion for accessibility and use hardware-accelerated properties for smooth 60fps performance.

@copilot

1. Simplify the emoji animation slightly so there's less motion and use the same motion on the emoji for all of them
2. Speed up the emoji select animation slightly
3. Remove all hover animation but keep press/hold animations
4. Remove header / title bar animations
5. Animate color changes (like in the settings and calendar pages)
6. Try to follow Material Design 3 Expressive principles

@copilot

1. Simplify the emoji animation slightly so there's less motion and use the same motion on the emoji for all of them
   ...

Refined animations following MD3 Expressive principles in commit 26cd727:

1. Simplified emoji animation:

• All emojis now use the same smooth scale animation (no more unique motions per emoji)
• Reduced complexity while keeping special effects (rain, sunshine, stars, etc.)

2. Faster animation:

• Reduced from 1.4s to 1.0s for snappier feel
• Uses MD3 Expressive easing: cubic-bezier(0.05, 0.7, 0.1)

3. Removed hover animations:

• All hover scale/transform effects removed
• Only press/active states remain (scale 0.9-0.96 on press)
• Consistent 0.1s press feedback across all interactive elements

4. Removed header animations:

• Page header now appears instantly (no slide-down)
• Loading text pulse removed

5. Added color transitions:

• 0.2-0.3s smooth transitions on all background/border color changes
• Applied to: buttons, cards, inputs, toggles, calendar days, toolbar, header
• Uses MD3 easing: cubic-bezier(0.2, 0, 0, 1)

6. MD3 Expressive principles:

• Consistent timing curves across similar interactions
• Quick press feedback (0.1s)
• Smooth color transitions (0.2-0.3s)
• Reduced motion complexity
• Hardware-accelerated animations only

@copilot

1. Add an option in Personalization to turn off "extra" animations which for now will only be considered as the emoji animations
2. Fix the missing color animation when switching theme mode in Settings
3. Only slide in cards, not all the stuff inside them independently
4. Think of a new animation for creating new notes
5. Remove all press animations except for the calendar days
6. Make the import/export loading screen smoother by letting it render while the background work is happening, so it doesn't freeze

And fix merge conflicts / build
