Over a two-month period, HJJ13 contributed to the haggis78/Nexus repository by expanding sandbox resources with new image assets, focusing on asset provisioning and repository hygiene to streamline testing and onboarding. HJJ13 added two initial image assets and later delivered a set of five character avatar images to enrich UI previews and support consistent branding. The work emphasized traceability, with each asset addition linked to its character, and maintained a non-intrusive approach by avoiding changes to application logic. Using Git for version control and asset management, HJJ13’s contributions improved the repository’s readiness for frontend prototyping and asset-driven UI development.
