## CS461 Check-in: B (3) #8
Description
I meet all C-level requirements and improved commit quality with short, descriptive messages for each change. I added automated tests using Vitest and verified they pass using npm run test. I implemented a key piece of functionality: a search feature that filters sample holdings data by investor or ticker and updates the results dynamically.
All source files include documentation-style header comments describing their purpose, and shared values such as routes, UI spacing, colors, and sample data are centralized in constants.js to avoid magic values and duplication.
