  - Change font-family for button to 'Noto Sans', sans-serif
- Add font-family declarations for different languages in _typography.scss:
  - For English language (en), use 'Geist', sans-serif
  - For Simplified Chinese language (zh-cn, zh-sg), use 'Noto Sans', 'Noto Sans CJK SC', sans-serif
  - For Traditional Chinese language (zh-hk, zh-mo, zh-tw), use 'Noto Sans', 'Noto Sans CJK TC', sans-serif
  - For Japanese language (ja), use 'Noto Sans', 'Noto Sans CJK JP', sans-serif
