   @font-face — self-hosted WOFF2, sourced from Google Fonts (SIL OFL).
   Both families ship as variable fonts; the same file serves every weight
   we use via the wght axis. The browser only downloads the latin-ext subset
   when a glyph in that range is actually rendered (Romanian: ă â î ș ț).
   `font-display: swap` keeps LCP cheap; the system-fallback metric overrides
   below minimise CLS during the swap.
