System Requirements Document for hollow-start

1. Introduction

The project "hollow-start" aims to develop a simple, single-page design for a todo application. The primary audience for this application is everyday users seeking a warm and approachable interface to manage their tasks efficiently.

2. System Overview

The hollow-start project will deliver a single-page todo application that allows users to manage their tasks in a simple and user-friendly environment. The application will persist the task list on the local device, enabling users to return to the page and continue managing their todos seamlessly. The design will be warm and inviting, following the creative direction inspired by Pablo Stanley's design language.

2a. Product Interpretation and Delivery Boundary

The application is explicitly designed as a single-page interface, with no additional pages or complex navigation. It will be publicly accessible without requiring user authentication. The todo list will be stored locally on the user's device to ensure continuity and ease of use. The design constraints emphasize a warm, friendly, and approachable aesthetic, avoiding corporate or overly formal styles.

4. User Personas

Todo User

The Todo User is an individual looking to manage their tasks in a simple and pleasant environment. Their primary goal is to keep their tasks organized using a single-page interface. They interact with the application by adding, editing, and deleting tasks. Success for the Todo User is measured by the ease of managing tasks and the application's ability to persist data locally for continuity.

4. Edit Task: The user selects a task to edit, modifies the details, and saves changes.
5. Delete Task: The user clicks the delete button on a task card to remove it from the list.
6. Persistence: Tasks are automatically saved to local storage, ensuring they are available upon return.
7. Continuation: The user can close the application and return later to find their tasks intact.

The color palette will be warm and inviting, with friendly, rounded typography for all text elements.

8. Interaction Model & Motion Direction

• Interaction Model: Animated
