Why this pattern works

Study course selection, image-choice lesson, chess exercise. Compare the hierarchy and controls shown in these publisher previews, then test the corresponding behavior in your own app.

Design notes

Surface: Course selection · Image-choice lesson · Chess exercise
Navigation: A close control and visible lesson progress frame the task without adding competing destinations.
Layout: A plain course list leads into exercises with a progress bar, large answer targets, and an illustrated task area.
Density: Compare the space reserved for the primary task with secondary metadata. The previews retain promotional framing; evaluate target sizes in your implemented screen.
Color: White space, green progress, pastel answer cards, and playful illustrations.
Type: Use clear heading, body, and metadata levels. Keep interface text scalable and verify readability with the device text-size settings.
Pattern: Learning & feedback
States: Static publisher previews only. Loading, empty, error, offline, permission, and keyboard behavior have not been tested. Specify and verify those states in your own implementation.
Don't: Do not copy the app identity, proprietary artwork, or promotional claims. Screenshot order is not a verified flow, and the listing version does not date every image.

Source scope: publisher-provided App Store previews. Promotional framing is retained. These are static examples, not a tested or recorded user flow. Do not infer unseen interactions.

## Objective
Adapt the interaction and layout patterns below to my project. Use my own content and identity. Do not reproduce logos, proprietary copy, or brand assets.

## Acceptance criteria
- Existing project conventions, design tokens, working functionality, and unrelated changes are preserved.
- Two or three reference principles clearly support the user's task; conflicts are resolved in favor of usability and the existing product.
- Accessible platform-native components express the interface; use semantic HTML when the target is mobile web. Available licensed assets are used; important UI text is never rendered as a bitmap.
- Every visible control has a defined behavior. Loading, empty, error, success, disabled, and long-content states are specified where relevant. Demo data is clearly labeled.
- Navigation and content adapt at 375px, 768px, and 1440px without horizontal page overflow. Keyboard use, visible focus, labeled inputs, at least 44px touch targets, readable contrast, and reduced motion are supported.
- Verification distinguishes rendered behavior from proposals and identifies anything still requiring a backend or external service.

## Quality bar
Clear hierarchy, consistent spacing, restrained surfaces, and purposeful motion. Avoid decorative gradients, excessive cards, placeholder buttons, and invented metrics unless the project calls for them. Do not claim a feature is connected or tested without evidence.
