Design: Efficient Design System Integration

#### The Problem:

The Home Unite Us application is designed to be used by numerous host home organizations, each with unique branding. Displaying the Home Unite Us application in the organization's branding is preferred as it is an important way to build trust with both Guests and Hosts.

Updating the application branding each time a new organization begins using HUU is tedious and time consuming.

This issue focuses on defining which elements and attributes will be customizable. A separate issue will track the mechanism that allows Admin Coordinators to set custom attributes.

#### High Level Approach:

Create a systematic approach to integrate organization branding into the Home Unite Us application.

#### Goals and Success

Success for this issue is if customizable attributes and elements are clearly defined and documented.

#### Solution Alignment

##### Considerations
* Any updates needed to the existing design system eg for spacing

##### Supported Elements and Attributes for Customization
* Primary color
* Secondary color
* Logo

#### Task List

- [x] Establish a clear source of truth for the Home Unite Us design system, and include a link in this issue

#### Known limitations

* Only the elements and attributes listed above will be customizable (i.e., primary color, secondary color, logo), other attributes will be the same across customers in line with the HUU design system

#### Key Decisions

* In a future phase (not this issue), Coordinator Admin users should have the ability to assign and edit a primary color, secondary color, and logo
