/*
 * Self-hosted webfonts. Poppins for headings and card titles, Roboto for
 * everything else.
 *
 * **Self-hosted rather than loaded from Google Fonts, and not by preference.**
 * The client's CloudFront response headers policy sets a Content-Security-Policy
 * of `font-src 'self' data:` and `style-src 'self' 'unsafe-inline'`, so a
 * `fonts.googleapis.com` stylesheet and a `fonts.gstatic.com` font file are both
 * refused — silently, with a console violation and a page that renders in the
 * fallback stack. Widening the CSP to permit them is the wrong trade: it adds a
 * third-party origin to every page load to save 88KB that is already cached.
 *
 * **Linked from index.html rather than injected by the theme.** The browser
 * discovers these while the JS bundle is still downloading; a CssBaseline
 * `@font-face` block is not discovered until React has mounted, which is a
 * visible reflow on a cold load.
 *
 * The files are the latin and latin-ext subsets only. Everything this catalog
 * renders comes out of Confluence in English.
 *
 * To refresh: request the CSS from Google Fonts with a modern browser
 * User-Agent, take the `latin` and `latin-ext` faces, and download those woff2
 * files. Anything else and you get the woff/ttf fallbacks.

/*
 * Poppins is a static family, so each weight is its own file. Only the two the
 * designs use are here — SemiBold 600 and Bold 700. There is no Poppins 400:
 * body text is Roboto, and a synthesised regular would be nobody's decision.
