Feature Specification: Redesign - Unisono Application

Feature Branch: 003-redesign-you-find
Created: суббота, 11 октября 2025 г.
Status: Draft
Input: User description: "Redesign. You find the instructions in the file .context/redesign.md"

User Scenarios & Testing (mandatory)

User Story 1 - Responsive and Consistent User Experience (Priority: P1)

As a user, I want to access and interact with the application seamlessly across different devices (desktop, tablet, mobile) so that I can use it comfortably regardless of my screen size or input method.

Why this priority: This is the core of the redesign, ensuring accessibility and usability across all platforms.

Independent Test: A user can successfully complete a primary task (e.g., create a session, join a session) on a mobile device using touch input, and the UI adapts correctly to the screen size.

Acceptance Scenarios:

1. Given a user is on a desktop browser, When they resize the browser window to a mobile viewport, Then the application layout and elements adjust responsively according to Material 3 guidelines.
2. Given a user is on a mobile device, When they interact with any UI element, Then touch input is correctly registered and the element responds as expected.
3. Given a user navigates through different pages on a tablet, When the device orientation changes, Then the layout adapts smoothly without loss of functionality or content.

User Story 2 - Clear Branding and Professional Appearance (Priority: P1)

As a user, I want to see consistent branding (app name, logo, favicon) throughout the application so that I can easily identify the product and perceive it as professional and trustworthy.

Why this priority: Branding is fundamental for user recognition and trust, and it applies across all parts of the application.

Independent Test: A new user can identify the application by its name and logo on any page, and the favicon is visible in the browser tab.

Acceptance Scenarios:

1. Given a user is on any page of the application, When they look at the header/navigation, Then "Unisono" is clearly displayed as the app name.
2. Given a user opens the application in a browser, When the page loads, Then the specified logo is visible in the header and the favicon is displayed in the browser tab.

User Story 3 - Improved Readability and User-Friendly Language (Priority: P2)

As a user, I want to read clear, concise, and non-technical language within the application, and see session topics presented without unnecessary prefixes, so that I can easily understand information and focus on the content.

Why this priority: Enhances user experience by making the application more approachable and easier to understand.

Independent Test: A user can read and understand the purpose of a session topic without encountering technical jargon or redundant prefixes.

Acceptance Scenarios:

1. Given a user views a session topic, When the topic is displayed, Then the prefix "Session: " is not present.
2. Given a user interacts with any text content in the application, When they read the text, Then it avoids technical terms and uses ToTitleCase where appropriate, without excessive capitalization.

---

User Story 4 - Streamlined Interface (Priority: P3)

As a user, I want a clean and simple interface without unnecessary information, so that I can focus on the core functionality and avoid distractions.

Why this priority: Contributes to a less cluttered and more intuitive user experience.

Independent Test: A user can navigate the application and confirm that the session status is not visible, leading to a cleaner interface.

Acceptance Scenarios:

1. Given a user is on a session-related page, When they view the UI, Then the session status element is not displayed.

Edge Cases

• What happens when a user accesses the application on an extremely small or large screen size? The responsive design should gracefully handle these extremes, potentially by hiding less critical elements or providing scrollable areas.
• How does the system handle long session topics after removing the "Session: " prefix? The display should truncate or wrap gracefully without breaking the layout.
• What if the specified logo/favicon image fails to load? A fallback (e.g., a default icon or text) should be displayed to maintain a consistent user experience.

Requirements (mandatory)

Functional Requirements

• FR-001: The system MUST implement a responsive design that adapts to various screen sizes (desktop, tablet, mobile) and orientations, adhering to Material 3 guidelines.
• FR-002: The system MUST support touch interactions for all UI elements on touch-enabled devices.
• FR-003: The application MUST display the name "Unisono" consistently in all session states and relevant UI headers.
• FR-004: The application MUST display a specified logo in the UI and use it as the favicon.
• FR-005: The application MUST preserve the existing primary button color in the new design.
• FR-006: The application MUST remove the prefix "Session: " from all displayed session topics.
• FR-007: The application MUST avoid technical terms in user-facing copywriting.
• FR-008: The application MUST hide the session status display from the user interface.
• FR-009: The application MUST apply ToTitleCase formatting to appropriate text elements and avoid excessive capitalization.
• FR-010: The system MUST maintain all existing user flows and underlying business logic.
• FR-011: The application MUST NOT use placeholders in input fields.
• FR-012: For input fields with validation rules, the application MUST display these rules as a field description directly under the field.
• FR-013: The application MUST utilize Material 3 standard components for displaying error, empty, and loading states.
• FR-014: The application MUST adhere to basic accessibility best practices in its UI design and implementation.

Assumptions

• The existing user flow and business logic are stable and will not change during the redesign.
• A suitable logo and favicon image will be provided.
• The "primary color that the buttons now have" can be accurately identified and extracted for use in the new design.
• The application's current structure allows for the integration of Material 3 components and responsive design principles without a complete rewrite of core functionality.

Success Criteria (mandatory)

Measurable Outcomes

• SC-001: 95% of users report a positive experience when using the application on mobile devices.
• SC-002: The application's branding (name, logo, favicon) is consistently displayed across all pages and device types.
• SC-003: User feedback indicates that the application's language is clear, non-technical, and easy to understand.
• SC-004: The application's UI is perceived as clean and uncluttered by 90% of users.
• SC-005: The application successfully passes all existing functional tests after the redesign, ensuring no regression in core logic.
• SC-006: Mobile page load times are consistently under 2 seconds on a 3G network.
