# 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. ## Clarifications ### Session суббота, 11 октября 2025 г. - Q: What are the expected performance targets for the redesigned UI, specifically regarding page load times on mobile devices? → A: Page load under 2 seconds on 3G. - Q: How should the redesigned UI handle common error states (e.g., network disconnection, API failures) and empty states (e.g., no sessions available)? → A: Display Material 3 standard error/empty/loading components. - Q: Are there any specific security or privacy considerations for the UI redesign beyond preserving existing logic? → A: No additional UI-specific security/privacy requirements. - Q: What level of accessibility compliance (e.g., WCAG standard) is required for the redesigned UI? → A: Basic accessibility best practices. - Q: What are the requirements for UI-specific observability (e.g., tracking user interactions, UI performance metrics)? → A: No specific UI observability requirements beyond existing.
