Fixes issue #501
Improved the UI/UX of the website.

[Sean-Kenneth-Doherty]

I tested this locally. It builds, but I do not think this is ready to merge as a fix for #501.

Checks run:

• git diff --check main...HEAD passes
• pnpm build passes

Concerns:

• The PR includes generated .astro/* files. Those should be removed from the branch; they are local generated/cache files.
• Most of the user-facing diff is arbitrary palette changes: the app background changes from near-black to #c28e34, cards change to a strong red background, the hover overlay becomes bright green, and tags become gray/black. That is a large visual direction change, but the PR does not explain the design goal or how it resolves the broad UI/UX issue.
• The package.json name change may be reasonable as a separate cleanup, but it is unrelated to UI/UX and changes the package name shown in build output.
• The navbar CSS addition is mis-indented and adds a dark background on each nav link rather than addressing a specific UX problem.

For #501, I would keep the patch focused on one concrete UX improvement at a time, with before/after screenshots or a clear description of the interaction/readability problem being solved.
