Site-wide frontier upgrade: i18n, performance, night reading
hreflang alternates and og:locale now cover every page; the works catalog renders its first 24 cards without scripts; the runtime index payload slimmed from 2.06MB to about 0.14MB; sliced self-hosted Noto Serif fonts unify the bilingual serif voice; a system-following dark palette ships with a dark-viewport audit; three dead English archive links now point to WorldCat lookups.
