pub fn register_fonts(cx: &App) -> Result<()>Expand description
Register the bundled fonts with the gpui text system. Failure is non-fatal: the theme’s system fallbacks take over (same families the CSS stack names).
Your own fonts go through this same gpui API — add_fonts takes any bytes,
and theme::Theme::font_sans / theme::Theme::font_mono name which
family the components then paint with.
