display=optional gave browsers only ~100ms to fetch DM Serif Display before sticking with the system serif fallback — on any uncached visit that meant the hero "Deepstock" title rendered thin (system serif at weight 400) and never swapped to the thick display font. Back to display=swap: brief FOUT on first paint, but the bold serif is what users actually see. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
