name: frontend-design description: Create distinctive, production-grade frontend interfaces for the Clue Symptom Tracker. Use Podia-inspired warm, approachable aesthetics with energy-conscious design for chronic illness users. Generates pixel-perfect React Native code using NativeWind. license: Complete terms in LICENSE.txt

This skill guides creation of distinctive, production-grade frontend interfaces for Clue. The design language is Podia-inspired: warm, approachable, and energy-conscious for users with chronic illness and brain fog.

Architecture note (agent-driven UI)

• Why this matters: In web-landing-next, some “conversion UI” components (e.g. ValuePropScreen) are tightly coupled to onboarding agent output types and are rendered from the “summary” step after Q3.
• Rule of thumb: If a React component is user-facing UI, prefer placing it under a UI-oriented folder (src/components/...) or a clearly named neutral folder like src/agent-ui/... rather than src/backend/... to avoid misleading boundaries.

</Pressable>

Energy-Conscious UX Principles

1. Large touch targets: Minimum 48px, preferably 56px for primary actions
2. One-tap actions: Prefer toggles and chips over text input
3. Progressive disclosure: Show minimal UI upfront, expand on demand
4. Gentle transitions: Soft animations, no jarring movements
5. Clear hierarchy: One primary CTA per screen, secondary actions subtle
6. Forgiving interactions: Easy to undo, skip, or "do later"

Screen Structure

Copy// Standard onboarding screen
<SafeAreaView className="flex-1 bg-background-light">
  {/* Decorative blobs */}
  <DecorativeBlobs />

  {/* Content */}
  <View className="flex-1 px-6 pt-12">
    {/* Progress indicator */}
    <ProgressBar step={1} total={3} />

    {/* Title */}
    <Text className="font-display text-4xl font-semibold text-primary mb-3">
      Screen Title
    </Text>

    {/* Subtitle */}
    <Text className="text-gray-600 text-lg leading-relaxed mb-8">
      Helpful description
    </Text>

    {/* Scrollable content */}
    <ScrollView className="flex-1" showsVerticalScrollIndicator={false}>
      {/* Options */}

    <PrimaryButton title="Continue" />

Onboarding Q3 Widget Patterns

Anti-Patterns (AVOID)

CRITICAL: No Emojis

• ❌ NEVER use emojis in UI, code, or content — Emojis feel juvenile, inconsistent across platforms, and clash with our sophisticated Podia-inspired aesthetic. Use icons from our icon system instead.

General Design Anti-Patterns

• ❌ Generic fonts (Inter alone is fine, but pair with Fraunces for display)
• ❌ Pure white backgrounds (use warm cream #FDFBF9)
• ❌ Sharp corners on cards (always round 16px+)
• ❌ Heavy drop shadows (use soft, low-opacity shadows)
• ❌ Dense forms or multiple text inputs per screen
• ❌ Purple gradients on white (use warm pastels instead)
• ❌ Aggressive animations or transitions
• ❌ Small touch targets (minimum 48px)
• ❌ Stock photos of smiling people (use authentic, hopeful imagery)
• ❌ Abstract illustrations instead of product UI mockups
• ❌ Rainbow gradients (stick to single accent color per section)

Chronic Illness UX Anti-Patterns (CRITICAL)

• ❌ Judgmental iconography: Sad faces 😢, red angry faces, "awful" labels
• ❌ Streak gamification: "You broke your streak!" messages
• ❌ Color-coded judgment: Red = bad day (use neutral intensity scales instead)
• ❌ Guilt-inducing language: "You missed 3 days" without empathy
• ❌ Complex navigation: Nested menus requiring multiple taps
• ❌ Required daily logging: Must allow gaps without penalty
• ❌ Text-heavy inputs: Typing is hard with brain fog, use taps
• ❌ Bright flashy UI: Painful during migraines or sensory sensitivity
• ❌ Social feeds in tracking: Users want focus, not distraction
• ❌ One-size-fits-all scales: "6/10 is bad" — but for chronic pain, 6 might be a GOOD day

Language Anti-Patterns (Per Language of Care guidelines)

• ❌ "Bad day" → Use "High intensity day" (neutral)
• ❌ "You should..." → Use "You might try..." (permission)
• ❌ "Track everything" → Use "Track what matters to YOUR question"
• ❌ Generic messages → Personalize with user's context
• ❌ Clinical jargon without context → Use accessible language
