The Almanac Spire

What it is

Per-glossary-term detail pages at /glossary/[slug]. Refactored Mark CII Almanac into lib/glossary-data.ts as the single source of truth — the index, ~30 detail pages, and sitemap now all read the same array. Each term — All-State, Cadenza, Intonation, Tempo rubato, etc — gets its own dedicated, indexable URL with prev/next sibling nav, DefinedTerm + BreadcrumbList JSON-LD, and a share-friendly OG-aware metadata block. Why dedicated URLs over #anchors: anchor fragments don't rank as their own results in search. ~30 new long-tail surfaces with one source-of-truth array.
