feat: use montserrat as app font

[blackmammoth]

Summary

Updates the app’s main font to Montserrat.

What Changed

• Added Google Fonts preconnect links for fonts.googleapis.com and fonts.gstatic.com.
• Added the Montserrat stylesheet with weights 400, 500, 600, 700, and 800.
• Updated the global body font stack to use Montserrat first, with the existing system sans-serif stack as fallback.

Why

Montserrat gives the app a more consistent branded typography baseline while preserving reliable fallback behavior across modern browsers.

Browser Support

Google Fonts serves Montserrat in modern web font formats such as WOFF2, which are supported by all modern browsers. The app also retains the existing fallback stack:

-apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, sans-serif
