- Name and years right-aligned with justified intro text below
- Maintained flex layout for experience/project items to show logos side-by-side
- Compact badge sizing (7pt font) for print

PDF Download UX:

- Shows work-in-progress message directing users to Print Friendly feature
- Bilingual modal (English/Spanish) matching info modal styling
- Modal closable via backdrop click, X button, or Escape key
- Prevents accidental downloads of outdated PDFs

UI improvements:
