Implementation Plan: Redesign - Unisono Application

Branch: 003-redesign-you-find | Date: суббота, 11 октября 2025 г. | Spec: spec.md Input: Feature specification from /specs/[###-feature-name]/spec.md

Note: This template is filled in by the /speckit.plan command. See .specify/templates/commands/plan.md for the execution workflow.

Summary

Redesign the Unisono application UI to be responsive across devices, adhere to Material Design 3 guidelines, incorporate consistent branding ("Unisono" app name, logo, favicon), improve readability by removing "Session: " prefixes and avoiding technical jargon, streamline the interface by hiding session status, and ensure basic accessibility. The redesign will preserve existing user flows and business logic, with a performance goal of mobile page load under 2 seconds on 3G.

Technical Context

Language/Version: Node.js (LTS), TypeScript 5.x
Primary Dependencies: React, Material-UI / MUI
Storage: Browser Local Storage (for session state, backend is stateless)
Testing: npm test
Target Platform: Web (responsive design for desktop, tablet, mobile) Project Type: Web application
Performance Goals: Mobile page load under 2 seconds on 3G
Constraints: Preserve existing user flow and logic, Material Design 3 guidelines, specific color preservation, copywriting rules, hiding session status, text formatting.
Scale/Scope: Redesign of existing application UI for responsiveness, branding, readability, and streamlined interface.

Constitution Check

GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.

I. Defined Technology Stack

• Backend: Node.js - Consistent.
• Frontend: React - Consistent.
• UI Framework: Material Design 3 (Material-UI / MUI) - Consistent (FR-001, FR-013).
• Containerization: Docker - Consistent (implied by project structure). Status: Pass

II. UI/UX Consistency

All user interfaces MUST adhere to Material Design 3 principles and components. - Consistent (FR-001, FR-013). Status: Pass

III. Container-First Development

All application services and development environments MUST run within Docker containers. - Consistent (implied by project structure). Status: Pass

IV. Test-Driven Development (TDD)

New features and bug fixes MUST follow a Test-Driven Development approach. - Consistent (implied by project structure and general best practices). Status: Pass

V. API-First Design

The backend and frontend are decoupled and communicate via a well-defined API contract. The API contract SHOULD be defined and reviewed before implementation begins. - Consistent (implied by project structure). Status: Pass

Structure Decision: The project utilizes a web application structure with separate backend and frontend directories. The redesign primarily impacts the frontend directory.

Complexity Tracking

Fill ONLY if Constitution Check has violations that must be justified

Violation	Why Needed	Simpler Alternative Rejected Because
[e.g., 4th project]	[current need]	[why 3 projects insufficient]
[e.g., Repository pattern]	[specific problem]	[why direct DB access insufficient]
